Microbial desulfurization of organic sulfur compounds in petroleum. (1/233)

Sulfur removal from petroleum is important from the standpoint of the global environment because the combustion of sulfur compounds leads to the production of sulfur oxides, which are the source of acid rain. As the regulations for sulfur in fuels become more stringent, the existing chemical desulfurizations are coming inadequate for the "deeper desulfurization" to produce lower-sulfur fuels without new and innovative processes. Biodesulfurization is rising as one of the candidates. Several microorganisms were found to desulfurize dibenzothiophene (DBT), a representative of the organic sulfur compounds in petroleum, forming a sulfur-free compound, 2-hydroxybiphenyl. They are promising as biocatalysts in the microbial desulfurization of petroleum because without assimilation of the carbon content, they remove only sulfur from the heterocyclic compounds which is refractory to conventional chemical desulfurization. Both enzymological and molecular genetic studies are now in progress for the purpose of obtaining improved desulfurization activity of organisms. The genes involved in the sulfur-specific DBT desulfurization were identified and the corresponding enzymes have been investigated. From the practical point of view, it has been proved that the microbial desulfurization proceeds in the presence of high concentrations of hydrocarbons, and more complicated DBT analogs are also desulfurized by the microorganisms. This review outlines the progress in the studies of the microbial desulfurization from the basic and practical point of view.  (+info)

Overexpression of recombinant proteins with a C-terminal thiocarboxylate: implications for protein semisynthesis and thiamin biosynthesis. (2/233)

A facile and rapid method for the production of protein C-terminal thiocarboxylates on DNA-encoded polypeptides is described. This method, which relies on the mechanism of the cleavage reaction of intein-containing fusion proteins, can produce multi-milligram quantities of protein C-terminal thiocarboxylate quickly and inexpensively. The utility of this method for protein semisynthesis and implications for studies on the biosynthesis of thiamin are discussed.  (+info)

Heating garlic inhibits its ability to suppress 7, 12-dimethylbenz(a)anthracene-induced DNA adduct formation in rat mammary tissue. (3/233)

The present studies compared the impact of heating, either by microwave or convection oven, on the ability of garlic to reduce the in vivo bioactivation of 7,12-dimethylbenz(a)anthracene (DMBA) in 55-d-old female Sprague-Dawley rats. In study 1, rats were fed a semipurified casein-based diet and treated by gastric gavage thrice weekly for 2-wk with crushed garlic (0.7 g in 2 mL corn oil) or the carrier prior to DMBA treatment (50 mg/kg body weight). Providing crushed garlic reduced by 64% (P < 0.05) the quantity DMBA-induced DNA adducts present in mammary epithelial cells compared to controls. In study 2, microwave treatment for 60 s, but not 30 s, decreased (P < 0.05) the protection provided by garlic against DMBA-induced adduct formation. In study 3, allowing crushed garlic to stand for 10 min prior to microwave heating for 60 s significantly (P < 0.05) restored its anticarcinogenic activity. Microwave heating of garlic for 30 s resulted in a 90% loss of alliinase activity. Heating in a convection oven (study 4) also completely blocked the ability of uncrushed garlic to retard DMBA bioactivation. Study 5 revealed that providing either 0.105 micromol diallyl disulfide or S-allyl cysteine by gastric gavage thrice weekly for 2 wk was effective in retarding DMBA bioactivation but isomolar alliin was not. These studies provide evidence that alliinase may be important for the formation of allyl sulfur compounds that contribute to a depression in DMBA metabolism and bioactivation.  (+info)

Inhibitory effect of sulfur-containing compounds in Scorodocarpus borneensis Becc. on the aggregation of rabbit platelets. (4/233)

The inhibitory effects of three pure compounds isolated from wood garlic, 2,4,5-trithiahexane (I), 2,4,5,7-tetrathiaoctane (II), and 2,4,5,7-tetrathiaoctane 2,2-dioxide (III), on rabbit platelet aggregation induced by collagen, arachidonic acid, U46619, ADP (adenosine 5'-diphosphate), PAF (platelet aggregating factor), and thrombin were studied in vitro. The anti-aggregating activity of 2,4,5,7-tetrathiaoctane 4,4-dioxide (IV) was also measured with collagen and arachidonic acid. I, II, III, and IV inhibited the platelet aggregation induced by all tested agonists. I, II, and III exhibited a stronger inhibitory effect against the thrombin-induced aggregation of GFP (gel-filtered platelets) than against the aggregation induced by the other agonists. Notably, the IC50 value for III was 4 microM, which is approximately 2.5 times stronger than MATS (methyl allyl trisulfide), a major anti-platelet compound isolated from garlic. In inhibiting collagen-induced aggregation, II was as potent as MATS and aspirin, with a marked disaggregation effect on the secondary aggregation by arachidonic acid, at the rate of 47.05%/min at a concentration of 10(-4) M. I, II, and III also suppressed U46619-induced aggregation. These results suggest that sulfur-containing compounds in wood garlic not only inhibit arachidonic acid metabolism but also suppress aggregation in association with the function of the platelet plasma membrane.  (+info)

Modulation of fibroblast growth factor-2 receptor binding, signaling, and mitogenic activity by heparin-mimicking polysulfonated compounds. (5/233)

Basic fibroblast growth factor (FGF-2) interacts with high-affinity tyrosine-kinase fibroblast growth factor receptors (FGFRs) and low-affinity heparan sulfate proteoglycans (HSPGs) in target cells. Both interactions are required for FGF-2-mediated biological responses. Here we report the FGF-2 antagonist activity of novel synthetic sulfonic acid polymers with distinct chemical structures and molecular masses (MMs). PAMPS [poly(2-acrylamido-2-methyl-1-propanesulfonic acid)], (MM approximately 7,000-10,000), PAS [poly(anetholesulfonic acid)], (MM approximately 9,000-11,000), PSS [poly(4-styrenesulfonic acid)], (MM = 70,000), and poly(vinylsulfonic acid) (MM = 2,000), inhibited FGF-2 binding to HSPGs and FGFRs in fetal bovine aortic endothelial GM 7373 cells. They also abrogated the formation of the HSPG/FGF-2/FGFR ternary complex, as evidenced by their capacity to prevent FGF-2-mediated cell-cell attachment of FGFR-1-overexpressing, HSPG-deficient Chinese hamster ovary cells to wild-type HSPG-bearing cells. Direct interaction of the polysulfonates with FGF-2 was demonstrated by their ability to protect the growth factor from proteolytic cleavage. Accordingly, molecular modeling, based on the crystal structure of the interaction of FGF-2 with a heparin hexamer, showed the feasibility of docking PAMPS into the heparin-binding domain of FGF-2. In agreement with their FGF-2-binding capacity, PSS, PAS, and PAMPS inhibited FGF-2-induced cell proliferation in GM 7373 cells and murine brain microvascular endothelial cells. The antiproliferative activity of these compounds was associated with the abrogation of FGF-2-induced tyrosine phosphorylation of FGFR-1. Moreover, the polysulfonates PSS and PAS inhibited FGF-2-induced activation of mitogen-activated protein kinase-1/2, involved in FGF-2 signal transduction. In conclusion, sulfonic acid polymers bind FGF-2 by mimicking heparin interaction. These compounds may provide a tool to inhibit FGF-2-induced endothelial cell proliferation in angiogenesis and tumor growth.  (+info)

Effects of nonsulfur and sulfur amino acids on the regulation of hepatic enzymes of cysteine metabolism. (6/233)

To determine the role of nonsulfur vs. sulfur amino acids in regulation of cysteine metabolism, rats were fed a basal diet or diets supplemented with a mixture of nonsulfur amino acids (AA), sulfur amino acids (SAA), or both for 3 wk. Hepatic cysteine-sulfinate decarboxylase (CSDC), cysteine dioxygenase (CDO), and gamma-glutamylcysteine synthetase (GCS) activity, concentration, and mRNA abundance were measured. Supplementation with AA alone had no effect on any of these measures. Supplementation of the basal diet with SAA, with or without AA, resulted in a higher CDO concentration (32-45 times basal), a lower CSDC mRNA level (49-64% of basal), and a lower GCS-heavy subunit mRNA level (70-76%). The presence of excess SAA and AA together resulted in an additional type of regulation: a lower specific activity of all three enzymes was observed in rats fed diets with an excess of AA and SAA. Both SAA and AA played a role in regulation of these three enzymes of cysteine metabolism, but SAA had the dominant effects, and effects of AA were not observed in the absence of SAA.  (+info)

Transformation of sulfur compounds by an abundant lineage of marine bacteria in the alpha-subclass of the class Proteobacteria. (7/233)

Members of a group of marine bacteria that is numerically important in coastal seawater and sediments were characterized with respect to their ability to transform organic and inorganic sulfur compounds. Fifteen strains representing the Roseobacter group (a phylogenetic cluster of marine bacteria in the alpha-subclass of the class Proteobacteria) were isolated from seawater, primarily from the southeastern United States. Although more than one-half of the isolates were obtained without any selection for sulfur metabolism, all of the isolates were able to degrade the sulfur-containing osmolyte dimethyl sulfoniopropionate (DMSP) with production of dimethyl sulfide (DMS). Five isolates also degraded DMSP with production of methanethiol, indicating that both cleavage and demethylation pathways for DMSP occurred in the same organism, which is unusual. Five isolates were able to reduce dimethyl sulfoxide to DMS, and several isolates also degraded DMS and methanethiol. Sulfite oxygenase activity and methanesulfonic acid oxygenase activity were also present in some of the isolates. The ability to incorporate the reduced sulfur in DMSP and methanethiol into cellular material was studied with one of the isolates. A group-specific 16S rRNA probe indicated that the relative abundance of uncultured bacteria in the Roseobacter group increased in seawater enriched with DMSP or DMS. Because this group typically accounts for >10% of the 16S ribosomal DNA pool in coastal seawater and sediments of the southern United States, clues about its potential biogeochemical role are of particular interest. Studies of culturable representatives suggested that the group could mediate a number of steps in the cycling of both organic and inorganic forms of sulfur in marine environments.  (+info)

An anti-platelet agent, OPC-29030, inhibits translocation of 12-lipoxygenase and 12-hydroxyeicosatetraenoic acid production in human platelets. (8/233)

1. In human platelets, arachidonic acid is mainly metabolized by the two enzyme systems; cyclo-oxygenase and 12-lipoxygenase. Cyclo-oxygenase produces prostaglandin H(2) which is further converted to thromboxane B(2). 12-Lipoxygenase synthesizes 12(S)-hydroperoxyeicosatetraenoic acid which is reduced to 12(S)-hydroxyeicosatetraenoic acid (12(S)-HETE). 2. An anti-platelet compound, OPC-29030, dose-dependently inhibited 12(S)-HETE production with an IC(50) of 0.06+/-0.01 microM, but not synthesis of thromboxane B(2) in human platelets. Although the compound suppressed 12(S)-HETE production in human platelets, cytosolic 12-lipoxygenase activity was not inhibited up to 10 microM. Essentially identical data were obtained with a 12-lipoxygenase of human erythroleukaemia cells which had megakaryocyte/platelet-like properties. 3. OPC-29030 also suppressed production of 5(S)-HETE, a 5-lipoxygenase product, in rat basophilic leukaemia cells without inhibiting enzyme activity. It has been shown that 5-lipoxygenase binds to membrane 5-lipoxygenase-activating protein (FLAP) to produce 5(S)-HETE, and thus FLAP inhibitor suppresses cellular 5(S)-HETE production. 4. A FLAP inhibitor, L-655,238, suppressed platelet 12(S)-HETE production, but had no effect on the 12-lipoxygenase activity. 5. Western blot analysis showed that platelet 12-lipoxygenase translocated from cytosol to membranes upon thrombin stimulation, and OPC-29030 suppressed this process in a dose-dependent manner. 6. These results suggest that the 12-lipoxygenase of human platelets binds to FLAP or a similar protein, and OPC-29030 suppresses 12(S)-HETE production by inhibiting a certain step of the 12-lipoxygenase translocation.  (+info)

One of the most promising benefits of oral probiotics is in treating malodor. About 25% of people suffer from malodor, and it has many social implications that affect a persons overall confidence and well-being. [6] With many causes for bad breath, 85% of the time breath malodor arises from insufficient oral hygiene, this conditions in the mouth favor the formation of offensive smelling volatile sulfur compounds (VSCs). [5] This is where dental probiotics can help to combat bad breath in a way that has not been widely considered. Dental probiotics focus on promoting the growth of good bacteria in the oral cavity and curtailing the growth of pathogenic bacteria. [5] With dental probiotics, daily exposure helps to colonize the oral cavity with bacteria that do not produce VSCs. Research has shown that 85% of people who took oral probiotics for one week experienced a significant reduction in volatile sulfur compounds.[7] Even more impressive is the fact that the majority of study participants ...

Sulphur (S) is an essential element for all living organisms. The uptake, assimilation and metabolism of S in plants are well studied. However, the regulation of S homeostasis remains largely unknown. Here, we report on the identification and characterisation of the more sulphur accumulation1 (msa1-1) mutant. The MSA1 protein is localized to the nucleus and is required for both S adenosylmethionine (SAM) production and DNA methylation. Loss of function of the nuclear localised MSA1 leads to a reduction in SAM in roots and a strong S-deficiency response even at ample S supply, causing an over- accumulation of sulphate, sulphite, cysteine and glutathione. Supplementation with SAM suppresses this high S phenotype. Furthermore, mutation of MSA1 affects genome-wide DNA methylation, including the methylation of S-deficiency responsive genes. Elevated S accumulation in msa1-1 requires the increased expression of the sulphate transporter genes SULTR1;1 and SULTR1;2 which are also differentially ...

United States Patent Filed Feb. 23, 1961, Ser. No. 90,941 (Ci. 2il-208) This invention relates to a process for the catalytic desulfurization of hydrocarbon oils containing cyclic and/or acyclic sulfur compounds. It is known to desulfurize hydrocarbon oils by contaoting these oils with a catalyst in the presence of hydrogen at elevated temperature and pressure. The drawback of this hydrosulfurization is that it requires hydrogen. It is also known to catalytically desulfurize hydrocarbon oils containing cyclic and acyclic sulfur compounds without using free hydrogen. Thus, US. Patent 2,151,721 describes a two-stage process for the desulfurizing of hydrocarbon fractions in which non-heteroeyclic sulfur compounds, for example aliphatic and aromatic mercaptans, are decomposed in the first stage by means of a catalyst of the clay type such as bauxite and fullers earth or of the metal oxide type, whereas in the second stage the heterooyclic sulfur compounds, for example thiophenes, are decomposed ...

The sea to air flux of CO2 and the biogenic volatile sulfur compound dimethylsulphide were assessed with the Relaxed Eddy Accumulation (REA) and the Gradient Flux techniques from stationary and moving platforms in the Atlantic and Pacific Oceans during the FAIRS and GasEx cruise. The correlation between the techniques was good, with REA on average higher than GF. Fluxes derived from micrometeorological measurements agreed within error bars with those obtained by the conventional equations as proposed by Liss and Merlivat (1986), Wanninkhof (1992), and Jacobs (1999). The relationships between the transfer velocity and wind speed based on the micrometeorological measurements agreed within 10% and were on average higher than the equation proposed by Wanninkhof (1992). The effect of temperature on the computed sea to air flux of CO2 were investigated on a micrometeorological scale as well as on a small scale (top few metres of the watercolumn). The definition of skin temperature relies on a known ...
Sulfur is an essential element for life and the metabolism of organic sulfur compounds plays an important role in the global sulfur cycle. Sulfur occurs in various oxidation states ranging from +6 in sulfate to -2 in sulfide (H2S). Sulfate reduction can occur in both an energy consuming assimilatory pathway and an energy producing dissimilatory pathway. The assimilatory pathway, which is found in a wide range of organisms, produces reduced sulfur compounds for the biosynthesis of S-containing amino acids and does not lead to direct excretion of sulfide. In the dissimilatory pathway, which is restricted to obligatory anaerobic bacterial and archaeal lineages, sulfate (or sulfur) is the terminal electron acceptor of the respiratory chain producing large quantities of inorganic sulfide. Both pathways start from the activation of sulfate by reaction with ATP to form adenylyl sulfate (APS). In the assimilatory pathway [MD:M00176] APS is converted to 3-phosphoadenylyl sulfate (PAPS) and then reduced ...

Y1 - 2006/12/1. N2 - Adsorptive desulfurization of a model fuel over CeO2-based adsorbents was conducted in a flowing adsorption system at 25 oC under ambient pressure without using H2 gas in order to evaluate the desulfurization performance of the adsorbent for producing ultra-low-sulfur fuel. For adsorption test, the capacity and selectivity of CeO2-based adsorbents for various sulfur compounds and the co-existing olefin and aromatic compound were used. Doping Ti and W into CeO2 significantly improved the sulfur removing capacity. The breakthrough sequence of the compounds over the CeO2-based adsorbents was, 1-C8 olefin °Ö toluene , thiophene , benzothiophene , 2-methyl benzothiophene , tetrahydrothiophene. By comparison of selectivity study and computational analysis, it was found that the electron ...
Capravirine, a non-nucleoside reverse transcriptase inhibitor for the treatment of human immunodeficiency virus type 1, undergoes extensive oxygenations to numerous sequential metabolites in humans. Because several possible oxygenation pathways may be involved in the formation and/or sequential metabolism of a single metabolite, it is very difficult or even impossible to determine the definitive pathways and their relative contributions to the overall metabolism of capravirine using conventional approaches. For this reason, a human liver microsome-based sequential incubation method has been developed to deconvolute the complicated sequential metabolism of capravirine. In brief, the method includes three fundamental steps: 1) 30-min primary incubation of [14C]capravirine, 2) isolation of 14C metabolites from the primary incubate, and 3) 30-min sequential incubation of each isolated 14C metabolite supplemented with an ongoing (30 min) microsomal incubation with nonlabeled capravirine. Based on ...

Sulfur is an essential component of all living cells. It is either the seventh or eighth most abundant element in the human body by weight, about equal in abundance to potassium, and slightly greater than sodium and chlorine. A 70 kg (150 lb) human body contains about 140 grams of sulfur. In plants and animals, the amino acids cysteine and methionine contain most of the sulfur, and the element is present in all polypeptides, proteins, and enzymes that contain these amino acids. In humans, methionine is an essential amino acid that must be ingested. However, save for the vitamins biotin and thiamine, cysteine and all sulfur-containing compounds in the human body can be synthesized from methionine. The enzyme sulfite oxidase is needed for the metabolism of methionine and cysteine in humans and animals. Disulfide bonds (S-S bonds) between cysteine residues in peptide chains are very important in protein assembly and structure. These covalent bonds between peptide chains confer extra toughness and ...

But, before we start feeling bad for anyone with bad breath, it would be best to know the possible bad breath causes.. Bad breath, or halitosis, is usually caused by the presence of bacteria in the mouth. Bacteria also consume food and excrete wastes, just like humans do. The wastes produced by the bacteria are sulfur compounds, which are odorous and are usually one of the bad breath causes. But, we still have to consider that there are other factors which affect the odor of ones ...
Oral malodor is the scientific name given to halitosis (bad breath), which involves the sometimes repulsive or off scent of the breath that occurs during exhaled breathing. It doesn’t even have to come from an oral source, as there is a wide-range of factors that can contribute to halitosis [1]. Whether for personal or social reasons, bad breath is such an important condition that it is the third most common reason that sends people seeking dental assistance (after tooth decay and periodontal disease) [2].. A variety of outside factors can contribute to the development of bad breath, as we come in contact with odorous foods and an excess of lifestyle behaviors. Depending on your habits, bad breath is sometimes transient, meaning it disappears after eating, flossing, brushing the teeth, or rinsing with a mouthwash. Others suffer persistent bad breath (also known as chronic bad breath), which is much more serious and affects about 25% of the population in many different ways. Bad breath ...

WASHINGTON (Reuters) - Scientists have answered one of natures most pungent questions: what gives the worlds smelliest fruit its distinctive aroma. Scientists in Singapore said on Monday they have mapped the genome of the durian, known throughout Southeast Asia as the king of fruits for its unique smell, flavor and formidable spiny appearance. They identified a group of genes responsible for odor compounds called volatile sulfur compounds, and found that these genes become highly activated as the fruit ripens, driving its unusual smell. The durian smell has been described as a mix of an onion-like sulfury aroma with notes of sweet fruitiness and savory soup-seasoning. A key component of the durian smell are volatile sulfur compounds, or VSCs, which have been characterized as decaying, onion-like, rotten eggs, sulfury and fried shallots, said geneticist Bin Tean Teh, deputy director of the National Cancer Center Singapore, co-leader of the study published in the journal Nature Genetics. ...
Many people have bad breath that is not associated with foods or gum disease. Everybody has an epithelial lining or skin on the inside of their mouths, tongue, under the tongue, down the throat and up into the nose. This skin is constantly shedding and renewing itself. These epithelial cells are broken down by bacteria. Some people have a particular mix of bacteria that produces volatile sulphur compounds (VSCs) which have a rotten smell i.e. bad breath. Everybody has a different mix of bacteria in their mouths, resulting in a variety and intensity of rotten smells, ranging from no discernable smell (i.e. very little VSCs) to particularly noxious smells.. ...

Health issues where bad breath is a symptom:. ...
Bad breath (or halitosis) is an unpleasant odour which can occur from time to time or be long lasting.. The main cause of bad breath is in the mouth. We have millions of bacteria that live in the mouth, particularly on the back of the tongue and these bacteria feed on the food debris that accumulates in the mouth and between our teeth. The bacteria give off a sulphur compound and it is this that creates the bad odour. Smoking and drinking alcohol contribute to the unpleasant odour. There are other conditions which affect the airways and stomach that can lead to bad breath too.. Improving your oral hygiene is the most effective way to eliminate bad breath. Brushing teeth and tongue twice a day using fluoride toothpastes, as well as flossing, will remove the bacteria which generally removes the odour. Other things that help are -. ...
Sulfur is an essential element for growth and physiological functioning of plants. However, its content strongly varies between plant species and it ranges from 0.1 to 6% of the plants dry weight. Sulfates taken up by the roots are the major sulfur source for growth, though it has to be reduced to sulfide before it is further metabolized. Root plastids contain all sulfate reduction enzymes, but the reduction of sulfate to sulfide and its subsequent incorporation into cysteine predominantly takes place in the shoot, in the chloroplasts. Cysteine is the precursor or reduced sulfur donor of most other organic sulfur compounds in plants. The predominant proportion of the organic sulfur is present in the protein fraction (up to 70% of total sulfur), as cysteine and methionine (two amino acids) residues. Cysteine and methionine are highly significant in the structure, conformation and function of proteins. Plants contain a large variety of other organic sulfur compounds, as thiols (glutathione), ...
Tooth decay, commonly known as cavities, occurs when plaque remains on your teeth for an extended period of time, allowing the bacteria to eat away at the surfaces of your teeth and gums.

The study investigated the alcoholic fermentation (AF) of non-Saccharomyces yeasts, and the effect of mixed AF (non-Saccharomyces induced) and malolactic fermentation (MLF) on durian wine. Torulaspora delbrueckii Biodiva was selected from four non-Saccharomyces yeasts due to its higher production of alcohols and esters. Simultaneous inoculation (SIM) and sequential inoculation (Seq-I) of T. delbrueckii Biodiva and Saccharomyces cerevisiae EC-1118 produced more alcohols and acetyl esters. However, Seq-I of T. delbrueckii Biodiva and P. kluyveri FrootZen produced excessive ethyl acetate compared to SIM. The SIM of T. delbrueckii Biodiva and Oenococcus oeni PN4 improved sugars utilization and produced more esters than Seq-I and T. delbrueckii control. After fermentation, volatile sulfur compounds endogenous to durian were reduced to trace or even undetectable levels in durian wine. The sulfides might be converted into their corresponding thiols. The produced and the endogenous thiols were then ...
Nine times out of ten, bad breath is related to the condition of your mouths interior, specifically the type of bacteria that resides there. Bacteria spends most of its time consuming foods and excreting wastes. The wastes from some of those bacteria are sulfur compounds. Sulfur compounds are what ignite the bad-breath brush fire. The wastes that the bacteria in our mouth excrete and produce are truly some of the most unattractive smells.. Most of these compounds that cause bad breath are the waste products of anaerobic bacteria, which live under the gum without oxygen. Our mouths experience an ongoing battle for dominance between anaerobic bacteria and aerobic bacteria. It is the precise balance between these two types of bacteria that determines the quality of your breath.. A normal tongue is pink, textured, and slightly moist. When you stick out your tongue, if you see a white coating - that is dead bacteria that creates an oxygen free zone underneath where the bad breath causing bacteria ...
There are several causes of bad breath, but the most common is known as bacterial putrefaction. A variety of bacterial species eat up a variety of nutrients from food, saliva and dying cells, then produce several waste products known as volatile sulfur compounds (VSC), diamines and short chain fatty acids. All of these are quite pungent in smell and can easily emanate from the mouth into a nearby nose. The increased diversity of microbial species found in halitosis samples suggests that halitosis may be the result of complex interactions between several bacterial species. Main bacteria associated with halitosis include ...

The next reason that can be attributed to bad breath in children is the lack of saliva. This is precisely the reason why children who have halitosis have bad breath in the morning, since the salivary glands are inactive while they are asleep. The use of medicines like aspirin could decrease the saliva production. It is necessary since it acts as a natural cleanser that washes the mouth and aids in digestion.. Another one of the causes of bad breath in children is due to infections. This is because children are more susceptible to these. Respiratory infections and tonsillitis are major causes. Apart from that children who experience gastrointestinal disturbance and kidney infections are likely to have bad breath as well. Additionally, poor oral hygiene is another leading cause for this.. ...
The cure for bad breath can be achieved if you do away with the consumption of certain foods. Protein rich foods like meat and diary products should be eaten sparingly. Digestion of these foods is not usually complete and this may cause bad breath. Thus, in order to reduce the instances, ensure that you do not eat too much of the proteins foods.. In the process of having a cure for your bad breath, it is logical that you observe a good oral hygiene. This process should be done in the right way so that the right result would be achieved. If you are brushing your teeth, try receding gums mouthwash and add flossing to it so that trapped food particles can be eliminated. Sometimes these food particles could be the breeding ground for bacteria.. It is always good for you to run short of saliva. This is one way of which bacteria that causes bad breath breeds in the mouth. However, saliva dryness may be attributed to some allergens. Identify these allergens and get rid of them as a way of curing bad ...
For most people, the best way to treat bad breath is through proper brushing, flossing and using a tongue scraper. Since most bad breath bacteria are anaerobic (without oxygen), they die in the presence of oxygen. Brushing your teeth with toothpaste, flossing and then scraping the film off of your tongue are all ways to scrub off bacteria and expose them to oxygen.. Mouth rinses such as Listerine, chlorhexidine gluconate and chlorine dioxide are chemical ways to kill the germs that cause bad breath. Alcohols can kill bacteria, and the ingredients in mouth rinses that have eucalyptol, menthol and thymol are all effective ways to reduce bacterial levels.. Foods can also cause bad breath. In fact, onion, garlic and certain vegetables contain oils that can remain on your tongue and between your teeth. You can even smell them through the pores in your skin. You can try a breath mint, but most do very little to get rid of these smells after you eat the food.. ...

Mouthwashes are generally ineffective on bad breath. If your bad breath persists even after good oral hygiene, there are special products your dentist may prescribe, including Zytex, which is a combination of zinc chloride, thymol and eucalyptus oil that neutralizes the sulfur compounds and kills the bacteria that causes them. In addition, a special antimicrobial mouth rinse may be prescribed. An example is chlorhexidine, but be careful not to use it for more than a few months as it can stain your teeth. Some antiseptic mouth rinses have been accepted by the American Dental Association for their breath freshening properties and therapeutic benefits in reducing plaque and gingivitis. Instead of simply masking breath odor, these products have been demonstrated to kill the germs that cause bad breath. Ask your dentist about trying some of these products.. ...
The hybrid sulfur (HyS) cycle is being developed as a technology to generate hydrogen by splitting water, using heat and electrical power from a nuclear or solar power plant. A key component is the SO 2-depolarized electrolysis (SDE) cell, which reacts SO 2 and water to form hydrogen and sulfuric acid. SDE could also be used in once-through operation to consume SO 2 and generate hydrogen and sulfuric acid for sale. A proton exchange membrane (PEM) SDE cell based on a PEM fuel cell design was fabricated and tested. Measured cell potential as a function of anolyte pressure and flow rate, sulfuric acid concentration, and cell temperature are presented for this cell. Sulfur accumulation was observed inside the cell, which could have been a serious impediment to further development. A method to prevent sulfur formation was subsequently developed. As a result, this was made possible by a testing facility that allowed unattended operation for extended periods. ...

Combustion of sulfur components of fossil fuels such as oil causes the emission of SO2 in the atmosphere and lead to the formation of acidic rain in the environment. The conventional approach for desulfurization of fossil fuels is the chemical procedure of hydrodesulfurization (HDS). However, this method has low efficiency for desulfurization of ring components of sulfur such as dibenzothiophene (DBT) that include a significant percentage of the total sulfur content of fossil fuel. biodesulfurization (BDS), is a biological method proposed for desulfurization of ring components of sulfur which is a non-destructive pathway to remove sulfur from hydrocarbons of petroleum in the mild conditions which potentially used as complementary with HDS. For industrial application of BDS, the approach needs the new challenge to enhance desulfurization activity by genetic engineering methods and bioreactor development to achieve from a fantasy technique to an industrial and reality method for reduction of sulfur
Halitosis is a common symptom which can affect people of all ages. It may decrease self confidence and social interactions. Oral halitosos is the consequence of microbial (mainly Gram negative bacteria) breakdown of food debris, cells, saliva, and blood. The agents that give rise to halitosis include especially the volatile sulphur compounds (VSC), diamines, and short chain fatty acids of which only the VSC can be detected in the clinical setting, making the detection of halitosis often very hard. The most common cause for oral halitosis is poor oral hygiene due to gingivitis or periodontitis. Other causes include bacterial accumulation on the posterior tongue, tonsillitis and others. Dry mouth has been implicated as a potential cause in halitosis.. Due to the lack of quantitative objective measuring to the severity of halitosis and especially in the face of the subjective nature of halitosis as occurs commonly a subjectively measurement is necessary. As no current QOL exists for measurement of ...
The BANA test (referring to the enzymatic breakdown of [N-benzoyl-dL-arginine-2-napthylamide]) is used to determine the proteolytic activity of certain oral anaerobes that contribute to oral malodor. Some bacteria, e.g. Prophyromona gingivalis, Treponema denticola, and Bacteroides forsythus (Red complex) produce waste products that are quite odiferous, and as a result contribute to bad breath. When a sample of a patients saliva that contains these bacteria is placed within the BANA testing compound, it causes the breakdown of the N-benzoyl enzyme. As a result of this biodegradation occurs, the test compound changes color, indicating a positive reaction. Uses: Used to identify volatile Sulphur compounds in halitosis patients. Metabolism ...
Bacteria. But just ordinary bacteria, and certainly not the bacteria that your toothbrush is style to remove. They are bacteria that reside in your teeth and gums and that covert sugars to acids. The acids then consume away at your tooth enamel till you have a cavity. No, the bacteria that cause chronic bad breath are what exactly are recognized as anaerobic bacteria; bacteria that thrive within the absence of oxygen.. These bacteria live in fissures deep inside your tongue and cheeks where there is no oxygen, at least not sufficient to deter anaerobic bacteria. They produce noxious waste products called volatile sulfur compounds (VSC), that really smell very bad. A white coating in your tongue can indicate which you possess a very serious infestation of these bacteria, even though you do not need a great deal to provide you with chronic bad breath.. The development of anaerobic bacteria could be encouraged by a dry mouth, where theres small saliva to penetrate the cracks inside your mouth and ...
According to recent studies, almost half the population of adults in North America suffers at least occasionally from bad breath (halitosis). The most common cause of bad breath is bacteria in the mouth and on the back of the tongue. These bacteria produce a volatile sulfur compound, which in turn produces a smell similar to rotten eggs. Other causes of halitosis include certain foods, smoking, alcohol, hormonal changes or simply being hungry ...
Diagnosis. A dentist or physician may notice bad breath during an office visit. Sometimes, the smell of the patients breath may suggest a likely cause for the problem. For example, fruity breath may be a sign of uncontrolled diabetes. A urine-like smell, especially in a person who is at high risk of kidney disease, can sometimes indicate kidney failure. Your dentist will review your medical history for conditions that can cause bad breath and for medicines that can cause dry mouth. Your dentist also will ask you about your diet, personal habits (smoking, chewing tobacco) and any symptoms. He or she also will ask who noticed the bad breath and when. Your dentist will examine your teeth, gums, mouth and salivary glands. He or she also will feel your head and neck and will evaluate your breath when you exhale from your nose and from your mouth. Your dentist may refer you to your family physician if an illness is the most likely cause. In severe cases of gum disease, your dentist may suggest that ...
For any individual the exact status of their breath can be difficult to ascertain. The reason for this lies in the fact that the oral cavity, the source of our breath, is connected to our nose by way of an opening which lies in the back of our mouth (back in the region of our soft palate). Since noses tend to filter out and ignore background odors, it filters out and ignores our own bad breath. This means it is quite possible for a person to have bad breath (halitosis), yet not be aware of it.. Here are three common causes of bad breath: ...
Bad breath (halitosis) in toddlers tends to surprise parents as it is generally thought to occur only in grown-ups. Leftover food particles could cause breath odor in a healthy child. Food particles can be stuck between the teeth, at the gum line, on the tongue, or on the surface of the tonsils. The resulting bacterial build-up will react with saliva and cause bad breath. Here are some causes of it as well as some common solutions to help you deal with your toddlers bad breath

The species representation of Thiobacilli was investigated in horizons F, H and A of spruce forest at ten localities. Concentrations of Thiobacilli in the selected localities and ability of the soils to oxidize sulphur compounds to sulphate were determined. Horizons F exhibited a high oxidative activity, a lower activity was found in horizon H and the lowest one was detected in horizon A. The activities showed spring and autumn maxima. Horizons F, H and A contained 104-105, 102-103 and 10l-103, respectively, Thiobacilli in 1 g dry soil.Thiobacillus thioparus was detected in all three horizons from all localities,T.thiooxidans was found in all horizons F, only in some horizons H and was not detected in horizons A.T.novellus was found only in some samples without any relation to the horizons,T. denitrificans was not detected at all.
Halitosis is a common problem in humans, and bad breath is largely caused by periodonitis, tongue debris, poor oral hygiene and badly fitted fillings, said Dr. Suzuki. Bacteria produce volatile compounds that smell unpleasant, including hydrogen sulphide, methyl mercaptan and dimethyl sulphide. Doctors often measure the levels of these compounds to diagnose the problem. Gastrointestinal diseases are also generally believed to cause halitosis.. Patients who were carrying H. pylori had more blood in their saliva and were also carrying Prevotella intermedia, which is one of the major periodontal bacteria.. Although the presence of H. pylori in the mouth does not directly cause bad breath, it is associated with periodontal disease, which does cause bad breath, said Dr. Suzuki. We now need to look into the relationship between H. pylori in the mouth and in the stomach. We hope to discover the role of the mouth in transmitting H. pylori stomach infections in the near future.. ...

Y1 - 1978/1/1. N2 - This research project investigated the feasibility of autotrophic denitrification as a nitrate removal process for municipal wastewater. The overall objective of this project was to evaluate the microbial kinetics, and to assess the process performance of autotrophic microbially mediated denitrification using sulfur electron donors. This study was divided into three experimental phases. Each phase utilized a different sulfur compound or flow configuration. Included in these phases were: continuous flow slurry-type with elemental sulfur as the electron source; semicontinuous flow, complete-mix reactors with thiosulfate or sulfide as the electron source; and packed bed columnar reactors with elemental sulfur as the electron source. Based on theoretical and experimental considerations, ...
When you make a habit of flossing, you remove food particles that can cause bad breath.. 2) Brush regularly - Plaque builds up around the enamel of each tooth when bacteria acts on carbohydrates. Brushing your teeth twice a day will help you shed the plaque buildup and remove food particles that lead to bad breath.. 3) Rinse after eating - Always rinse your mouth properly, after eating anything especially sugary food. A quick rinse after each meal goes a long way in maintaining a fresh breath.. 4) Drink Water Regularly - A dry mouth is convenient for bacteria activity. Drinking water regularly to keeps your mouth hydrated; it ensures you produce enough saliva and reduces the odds of developing bad breath.. 5) Scrape your tongue - The coating that gradually forms on your tongue can be a host for bacteria activity. After brushing your teeth, gently brush your tongue with your toothbrush to get rid of the coating on your tongue.. For more advice and help, consult a doctor online via The Reliance ...
