The alkene monooxygenase from Xanthobacter strain Py2 is closely related to aromatic monooxygenases and catalyzes aromatic monohydroxylation of benzene, toluene, and phenol. (1/497)

The genes encoding the six polypeptide components of the alkene monooxygenase from Xanthobacter strain Py2 (Xamo) have been located on a 4.9-kb fragment of chromosomal DNA previously cloned in cosmid pNY2. Sequencing and analysis of the predicted amino acid sequences indicate that the components of Xamo are homologous to those of the aromatic monooxygenases, toluene 2-, 3-, and 4-monooxygenase and benzene monooxygenase, and that the gene order is identical. The genes and predicted polypeptides are aamA, encoding the 497-residue oxygenase alpha-subunit (XamoA); aamB, encoding the 88-residue oxygenase gamma-subunit (XamoB); aamC, encoding the 122-residue ferredoxin (XamoC); aamD, encoding the 101-residue coupling or effector protein (XamoD); aamE, encoding the 341-residue oxygenase beta-subunit (XamoE); and aamF, encoding the 327-residue reductase (XamoF). A sequence with >60% concurrence with the consensus sequence of sigma54 (RpoN)-dependent promoters was identified upstream of the aamA gene. Detailed comparison of XamoA with the oxygenase alpha-subunits from aromatic monooxygenases, phenol hydroxylases, methane monooxygenase, and the alkene monooxygenase from Rhodococcus rhodochrous B276 showed that, despite the overall similarity to the aromatic monooxygenases, XamoA has some distinctive characteristics of the oxygenases which oxidize aliphatic, and particularly alkene, substrates. On the basis of the similarity between Xamo and the aromatic monooxygenases, Xanthobacter strain Py2 was tested and shown to oxidize benzene, toluene, and phenol, while the alkene monooxygenase-negative mutants NZ1 and NZ2 did not. Benzene was oxidized to phenol, which accumulated transiently before being further oxidized. Toluene was oxidized to a mixture of o-, m-, and p-cresols (39.8, 18, and 41.7%, respectively) and a small amount (0.5%) of benzyl alcohol, none of which were further oxidized. In growth studies Xanthobacter strain Py2 was found to grow on phenol and catechol but not on benzene or toluene; growth on phenol required a functional alkene monooxygenase. However, there is no evidence of genes encoding steps in the metabolism of catechol in the vicinity of the aam gene cluster. This suggests that the inducer specificity of the alkene monooxygenase may have evolved to benefit from the naturally broad substrate specificity of this class of monooxygenase and the ability of the host strain to grow on catechol.  (+info)

Methods for detection of Anticarsia gemmatalis nucleopolyhedrovirus DNA in soil. (2/497)

Two methods, phenol-ether and magnetic capture-hybridization (MCH), were developed and compared with regard to their sensitivities and abilities to extract the DNA of the insect baculovirus Anticarsia gemmatalis nucleopolyhedrovirus (AgMNPV) from soil and to produce DNA amplifiable by PCR. Laboratory experiments were performed with 0. 25 g of autoclaved soil inoculated with different viral concentrations to optimize both methods of baculovirus DNA extraction and to determine their sensitivities. Both procedures produced amplifiable DNA; however, the MCH method was 100-fold more sensitive than the phenol-ether procedure. The removal of PCR inhibitors from the soil appeared to be complete when MCH was used as the viral DNA isolation method, because undiluted aliquots of the DNA preparations could be amplified by PCR. The phenol-ether procedure probably did not completely remove PCR inhibitors from the soil, since PCR products were observed only when the AgMNPV DNA preparations were diluted 10- or 100-fold. AgMNPV DNA was detected in field-collected soil samples from 15 to 180 days after virus application when the MCH procedure to isolate DNA was coupled with PCR amplification of the polyhedrin region.  (+info)

Metabolism of [14C]phenol in the isolated perfused mouse liver. (3/497)

A previous report from this laboratory focused on the metabolism of [14C]benzene (BZ) in the isolated, perfused, mouse liver (C. C. Hedli, et al., 1997, Toxicol. Appl. Pharmacol. 146, 60-68). Whereas administration of BZ to mice results in bone marrow depression (R. Snyder et al., 1993, Res. Commun. Chem. Pathol. Pharmacol. 20, 191-194), administration of phenol (P), the major metabolite of BZ, does not. It was, therefore, of interest to determine whether the metabolic fate of P produced during BZ metabolism differed from that of P metabolized in the absence of BZ. Mouse livers were perfused with a solution of [14C]P in both the orthograde (portal vein to central vein) and retrograde (central vein to portal vein) direction to investigate the metabolic zonation of enzymes involved in P hydroxylation and conjugation. Perfusate samples were collected, separated by HPLC, and tested for radioactivity. Unconjugated metabolites were identified by comparing their retention times with nonradiolabeled standards, which were detected by UV absorption. Conjugated metabolites were identified and collected on the basis of radiochromatogram results, hydrolyzed enzymatically, and identified by co-chromatography with unlabeled BZ metabolites. The objective was to compare and quantify the metabolites formed during the perfusion of P in the orthograde and retrograde directions and to compare the orthograde P-perfusion results with the orthograde BZ results reported previously. Regardless of the direction of P perfusion, the major compounds released from the liver were P. phenylgucuronide, phenylsulfate, hydroquinone (HQ), and HQ glucuronide. A comparison of the results of perfusing P in the orthograde versus the retrograde direction showed that more P was recovered unchanged and more HQ was formed during retrograde perfusion. The results suggest that enzymes involved in P hydroxylation are generally closer to the central vein than those involved in conjugation, and that during retrograde perfusion, P metabolism may be limited by the sub-optimal conditions of perfusion. Comparison of the orthograde perfusion studies of P and BZ revealed that a larger percentage of the radioactivity released from the liver was identified as unconjugated HQ after BZ perfusion than after P perfusion. In addition, the amount of radioactivity covalently bound to liver macromolecules was measured after each perfusion and determined to be proportional to the amount of HQ and HQG detected in the perfusate samples.  (+info)

An outbreak of nonflocculating catabolic populations caused the breakdown of a phenol-digesting activated-sludge process. (4/497)

Activated sludge was fed phenol as the sole carbon source, and the phenol-loading rate was increased stepwise from 0.5 to 1.0 g liter-1 day-1 and then to 1.5 g liter-1 day-1. After the loading rate was increased to 1.5 g liter-1 day-1, nonflocculating bacteria outgrew the sludge, and the activated-sludge process broke down within 1 week. The bacterial population structure of the activated sludge was analyzed by temperature gradient gel electrophoresis (TGGE) of PCR-amplified 16S ribosomal DNA (rDNA) fragments. We found that the population diversity decreased as the phenol-loading rate increased and that two populations (designated populations R6 and R10) predominated in the sludge during the last several days before breakdown. The R6 population was present under the low-phenol-loading-rate conditions, while the R10 population was present only after the loading rate was increased to 1.5 g liter-1 day-1. A total of 41 bacterial strains with different repetitive extragenic palindromic sequence PCR patterns were isolated from the activated sludge under different phenol-loading conditions, and the 16S rDNA and gyrB fragments of these strains were PCR amplified and sequenced. Some bacterial isolates could be associated with major TGGE bands by comparing the 16S rDNA sequences. All of the bacterial strains affiliated with the R6 population had almost identical 16S rDNA sequences, while the gyrB phylogenetic analysis divided these strains into two physiologically divergent groups; both of these groups of strains could grow on phenol, while one group (designated the R6F group) flocculated in laboratory media and the other group (the R6T group) did not. A competitive PCR analysis in which specific gyrB sequences were used as the primers showed that a population shift from R6F to R6T occurred following the increase in the phenol-loading rate to 1.5 g liter-1 day-1. The R10 population corresponded to nonflocculating phenol-degrading bacteria. Our results suggest that an outbreak of nonflocculating catabolic populations caused the breakdown of the activated-sludge process. This study also demonstrated the usefulness of gyrB-targeted fine population analyses in microbial ecology.  (+info)

Taxonomic characterization of denitrifying bacteria that degrade aromatic compounds and description of Azoarcus toluvorans sp. nov. and Azoarcus toluclasticus sp. nov. (5/497)

A taxonomic characterization of twenty-one strains capable of degrading aromatic compounds under denitrifying conditions, isolated from ten different geographical locations, was performed on the basis of general morphological and physiological characteristics, cellular fatty acids, DNA base composition, small ribosomal (16S) subunit DNA sequences, whole-cell protein patterns and genomic DNA fragmentation analysis, in addition to DNA similarity estimations using hybridization methods. The collection of strains was subdivided into a number of different groups. A first group, consisting of four strains, could be assigned to the previously described species Azoarcus tolulyticus. A second group (five strains) had DNA which reannealed highly to that of strains of the first group, and it is considered to represent a genomovar of A. tolulyticus. The third and fourth groups, composed of a total of five strains, represent a new species of Azoarcus, Azoarcus toluclasticus (group 3) and a genomovar of this species (group 4), respectively. Finally, the fifth group, with two strains, corresponds to another new species of the genus Azoarcus, Azoarcus toluvorans. In addition to these five groups, the collection includes five individual strains perhaps representing as many different new species. The above classification is partially consistent with the results of approaches other than DNA-DNA hybridization (electrophoretic patterns of whole-cell proteins and of the fragments obtained after digestion of total DNA with infrequently cutting restriction enzymes). On the other hand, no correlation of these groupings was found in terms of the cellular fatty acid composition. It is also unfortunate that no simple sets of easily determinable phenotypic properties could be defined as being characteristic of each of the groups.  (+info)

Heat-induced expression and chemically induced expression of the Escherichia coli stress protein HtpG are affected by the growth environment. (6/497)

Differences in expression of the Escherichia coli stress protein HtpG were found following exposure of exponentially growing cells to heat or chemical shock when cells were grown under different environmental conditions. With an htpG::lacZ reporter system, htpG expression increased in cells grown in a complex medium (Luria-Bertani [LB] broth) following a temperature shock at 45 degrees C. In contrast, no HtpG overexpression was detected in cells grown in a glucose minimal medium, despite a decrease in the growth rate. Similarly, in pyruvate-grown cells there was no heat shock induction of HtpG expression, eliminating the possibility that repression of HtpG in glucose-grown E. coli was due to catabolite repression. When 5 mM phenol was used as a chemical stress agent for cells growing in LB broth, expression of HtpG increased. However, when LB-grown cells were subjected to stress with 10 mM phenol and when both 5 and 10 mM phenol were added to glucose-grown cultures, repression of htpG expression was observed. 2-Chlorophenol stress resulted in overexpression of HtpG when cells were grown in complex medium but repression of HtpG synthesis when cells were grown in glucose. No induction of htpG expression was seen with 2, 4-dichlorophenol in cells grown with either complex medium or glucose. The results suggest that, when a large pool of amino acids and proteins is available, as in complex medium, a much stronger stress response is observed. In contrast, when cells are grown in a simple glucose mineral medium, htpG expression either is unaffected or is even repressed by imposition of a stress condition. The results demonstrate the importance of considering differences in growth environment in order to better understand the nature of the response to an imposed stress condition.  (+info)

Novel effector control through modulation of a preexisting binding site of the aromatic-responsive sigma(54)-dependent regulator DmpR. (7/497)

The Pseudomonas derived sigma(54)-dependent DmpR activator regulates transcription of the (methyl)phenol catabolic dmp-operon. DmpR is constitutively expressed, but its transcriptional promoting activity is positively controlled in direct response to the presence of multiple aromatic effectors. Previous work has led to a model in which effector binding by the amino-terminal region of the protein relieves repression of an intrinsic ATPase activity essential for its transcriptional promoting property. Here, we address whether the observed differences in the potencies of the multiple effectors (i) reside at the level of different aromatic binding sites, or (ii) are mediated through differential binding affinities; furthermore, we address whether binding of distinct aromatic effectors has different functional consequences for DmpR activity. These questions were addressed by comparing wild type and an effector specificity mutant of DmpR with respect to effector binding characteristics and the ability of aromatics to elicit ATPase activity and transcription. The results demonstrate that six test aromatics all share a common binding site on DmpR and that binding affinities determine the concentration at which DmpR responds to the presence of the effector, but not the magnitude of the responses. Interestingly, this analysis reveals that the novel abilities of the effector specificity mutant are not primarily due to acquisition of new binding abilities, but rather, they reside in being able to productively couple ATPase activity to transcriptional activation. The mechanistic implications of these findings in terms of aromatic control of DmpR activity are discussed.  (+info)

Amount and fate of egg protein escaping assimilation in the small intestine of humans. (8/497)

Studies attempting to evaluate protein assimilation in humans have hitherto relied on either ileostomy subjects or intubation techniques. The availability of stable isotope-labeled protein allowed us to determine the amount and fate of dietary protein escaping digestion and absorption in the small intestine of healthy volunteers using noninvasive tracer techniques. Ten healthy volunteers were studied once after ingestion of a cooked test meal, consisting of 25 g of (13)C-, (15)N-, and (2)H-labeled egg protein, and once after ingestion of the same but raw meal. Amounts of 5.73% and 35.10% (P < 0.005) of cooked and raw test meal, respectively, escaped digestion and absorption in the small intestine. A significantly higher percentage of the malabsorbed raw egg protein was recovered in urine as fermentation metabolites. These results 1) confirm that substantial amounts of even easily digestible proteins may escape assimilation in healthy volunteers and 2) further support the hypothesis that the metabolic fate of protein in the colon is affected by the amount of protein made available.  (+info)

Biological treatment of hypersaline wastewaters such as fermentation brine from table olive processing (FTOP), was carried out using four sequential biological reactors (SBRs). These wastewaters were characterized by conductivities higher than 90 mS·cm-1 together with COD and total phenols concentration values of more than 15 g·L-1 and 1000 mg·L-1, respectively. In order to increase the organic removal efficiency and to reduce the hydraulic retention time (HRT), extra nutrients were added and pre-treatment by adsorption was performed. Results showed that the COD/N/P relationship, in the FTOP, of 250/5/1 was appropriate for the biological process reaching COD removal efficiencies of around 80%. The FTOP adsorption pre-treatment with powder activated carbon for the reduction of phenols concentration to 400 mg·L-1 led to a HRT reduction from 40 to 15 days, maintaining the COD and total phenols removal percentages around 78% and 97%, respectively.

Several activated carbons (ACs) were used as metal-free catalysts for degradation of a toxic organiccompound, phenol, in the presence of different oxidants, H2O2, peroxydisulfate (PS) and peroxymonosulfate (PMS). It was found that ACs were effective in heterogeneous activation of PMS toproduce sulfate radicals for degradation of phenol, much better than H2O2 and PS. Particle size of AC significantly influenced AC activity, and powder AC was much more effective than granular AC. The complete phenol removal could be achieved in 15 min on powder activated carbon (PAC) under the conditions of [phenol] = 25 mg L-1, [PAC] = 0.2 g L-1, [PMS] = 6.5 mmol L-1, and T = 25 degrees Celcius. It was also found that phenol degradation was significantly influenced by PMS loading, catalyst loading, phenol concentration and temperature. Surface activation of PMS and phenol adsorption played important roles in phenol degradation. Surface coverage by intermediate adsorption and structural change induced deactivation ...
Wastewaters from various types of industries contain different types of phenols. Phenolic compounds are toxic substances and some are known or suspected carcinogens. Therefore it is important to remove phenol and phenolic compounds from contaminated industrial and aqueous streams before discharged into any water bodies. It is well known that adsorption is an efficient method for removal of various pollutants from wastewater. Several adsorbents have been used for treatment of wastewater and removal of phenolic compounds. In the present study, efforts have been made for removal of phenol from aqueous solution using zeolite as an adsorbent. The adsorbent potential was tested on batch synthetic solutions containing 1-5 (mg/L) phenol concentration at room temperature. The influence of solution pH, adsorbent dose, contact time and initial phenol concentration on the removal efficiency of phenol from water was investigated. A 94 % phenol removal efficiency was obtained for an adsorption time of 4 hr at ...

The efficiency was significantly enhanced for electrochemically assisted photocatalysis; the average mineralization was 78% after 3 h and was almost complete after 6 h for a TiO2 electrode externally connected to a Pt counter-electrode and biased at +0.7 or +1.1 V with a potentiostat, or by a series connection to a solar cell. Phenol degradation exhibited pseudo-first-order kinetics, and application of the bias potential increased the rate constant from 0.21 to 0.47 h(-1). Applying a ...
The potential of rice husk and rice husk ash for phenol adsorption from aqueous solution was studied. Batch kinetics and isotherm studies were carried out under varying experimental conditions of contact time, phenol concentration, adsorbent dose and pH. Adsorption equilibrium of rice husk and rice husk ash was reached within 6 hours for phenolic concentration 150-500 ?g/L and 3 hours for phenol concentration 500-1300 ?g/L, respectively. Kinetics of adsorption obeyed a first-order rate equation. The adsorption of phenol increases with increasing the solution pH value. The suitability of the Freundlich and Langmuir adsorption models of the equilibrium data was investigated for each phenol-sorbent system. The results showed that the equilibrium data for all the phenol-sorbent systems fitted the Freundlich model best within the concentration range studied. A comparative study showed that rice husk ash is very effective than rice husk for phenol removal. The studies showed that the rice husk ash can be used

Phenol is an important chemical in biological research. It is used primarily for isolation and purification of DNA and RNA. Pure phenol is solid at room temperature. Almost all biochemical uses of phenol use a water saturated phenol solution, or a mixture of phenol in chloroform. The purity and pH of phenol solutions used in biochemical work is very important. Oxidized phenol can result in DNA damage, and cannot be used. The pH of phenol solutions dramatically changes the solubility of DNA. Phenol is effective at denaturing and precipitating most proteins, and is an effective means of purifying DNA or RNA from protein contaminants. Water saturated phenol is typically shipped and stored with an upper layer of buffer, containing Tris-HCl at the appropriate pH. It is important to pipet from the lower layer, which is the layer containing phenol. Phenol chloroform solutions are stored similarly. Phenol is sometimes stored with an antioxidant to preserve its quality. It should be stored refrigerated ...

Phenol is one of toxic pollutants in many kinds of hypersaline industrial effluents which should be treated properly before discharged into water bodies. In this work, a halophilic strain which could utilize phenol as the sole source of carbon and energy was isolated. Based on 16S rRNA results, it was identified as a member of Citrobacter. The phenol biodegradation ability and cell growth of the strain was evaluated with the variation of initial phenol concentration and salinity. The effect of temperature and pH on phenol removal was also investigated. The results showed that the strain was capable of withstanding high phenol (up to 1,100 mg L−1) environment with varying salinity conditions (0-10% of NaCl). The optimal initial phenol concentration was 400 mg L−1, with which the average removal rates of phenol peaked at 10.8 mg L−1 h−1. The higher initial concentration of phenol could inhibit the microbial metabolism. The optimal temperature, pH and salinity were 35 °C, 6.0, and 0%, ...
Phenols and its derivatives are environmental pollutant commonly found in many industrial effluents. It is toxic in nature and causes various health hazards. However, they are poorly removed in conventional biological processes due to their toxicity. Immobilization of microbial cells has received increasing interest in the field of waste treatment and creates opportunities in a wide range of sectors including environmental pollution control. Live cells of phenol-degrading yeast, Candida tropicalis RETL-Cr1, were immobilized on coconut husk and loofah by adsorption. The immobolized particle was packed into biofilter column which used for continuous treatment of a phenol with initial phenol concentration of 3mM. Both loofah and coconut husk have similar phenol biodegradation rate of 0.0188 gL-1h -1 within 15 hours to achieve a phenol removal efficiency of 100 %. However loofah have lower biomass concentration of 4.22 gL-1 compared to biomass concentration on coconut husk, 4.39 gL-1 . Coconut husk ...

In this investigation, single and hybrid immobilization techniques for whole cells of Pseudomonas sp. SA01 were employed to enhance phenol degradation rate. The single immobilization was achieved using alginate (2-4%) and pectin (3-5%) together with the combined immobilization systems which consisted of alginate-chitosan-alginate (ACA), polyvinyl alcohol (PVA)-alginate capsules. The freely suspended cellsof Pseudomonas sp. SA01 was able to degrade phenol in concentrations up to 1000 mg/L 84 h. The complete degradation of the same concentration of phenol by cells entrapped in alginate (3%), in hybrid immobilization system alginate-chitosan-alginate (ACA), and in PVA-alginate encapsulated cells were achieved as low as 30 h. However, the cells immobilized in pectin (5 %) could degrade the same concentration of phenol at 35 and 40 h respectively. The cell loading capacity is increased in PVA-alginate hybrid capsules owing to the reduction of cell leakage from the beads, resulted in higher activity ...

Introduction. 1. Give an account of the properties and uses of phenol. (1) Phenol is acidic and its conjugate base, phenoxide ion is stabilized by resonance. However, phenol is not acidic enough to liberate CO2 from phenol because an aqueous solution of carbon dioxide is a stronger acid than phenol. An aqueous solution of phenol has a pH value of 9. This means phenol reacts with NaOH but not NaHCO3. Phenol dissolves in NaOH(aq) to form sodium phenoxide, an ionic salt. (2) Phenol is corrosive and is a useful antiseptic. (3) Phenol is a colorless solid of low melting point. Its pink appearance is due to the presence of impurities. (4) When attached to a benzene ring, a hydroxyl group does not show the properties of an alcohol. The delocalization of electrons into the ring makes the -OH group inert towards replacement. On the other hand, the -OH group activates the ring toward electrophilic substitution at the ortho- and para-positions. Therefore, phenol reacts with (a) NO2+, (b) CH3+, (c) CH3CO+, ...

Phenols are chemicals found in basically all foods. The "phenol" category contains quite a few subgroups, both food and non-food. For example, salicylate is a subgroup of phenol. There are other chemicals found in foods that can cause similar symptoms as phenols, including amines, even tho they are not technically "phenol". For some children, their bodies have difficulty processing the phenols into useful or at least non-harmful substances. This condition is called PST deficiency. So you need to reduce your child s phenol intake, or help his body process them. Otherwise they build up to levels which can affect his behavior and physical condition. Here are the Feingold definitions of phenols and salicylates. Phenols -- "A group of natural and synthetic compounds that are ingested or produced to varying degrees by the body or by microbes in the intestine contain a benzene ring with one or more hydroxyl (OH) groups attached to it. When this attachment occurs, they become phenolic compounds. These ...

This report contains a preliminary process design for a direct route to phenol from benzene based on the 2009 patent issued to the Council of Scientific Research in New Delhi. This patent describes a significantly improved method to produce phenol using a vanadyl pyrophosphate catalyst. The process evades over-oxidized byproducts and yield loss. The resulting design produces the desired 500 million pounds per year of phenol by combining the ideas presented in the patent and adjustments made by the design group. The optimal process presented utilizes two parallel series of three reactors each to produce the phenol. Through a combination of azeotropic distillation and flash vaporization, it is possible to achieve greater than 99 percent pure phenol as a product while recycling all components not consumed. The plant requires a capital investment of 85.7 million USD with an internal rate of return of 4.98 percent and return on investment of 1.48 percent. It is suggested that the research and development
This study investigated the catabolic potential of a eukaryotic alga to degrade one of the most common organic pollutants, phenol. The alga, Ochromonas danica (993/28), was selected for study after screening for its heterotrophic capabilities. The catabolic versatility of the alga was elucidated by incubating with a variety of phenolic compounds. The alga removed phenol, all the cresol isomers and 3,4-xylenol from its incubation media, with phenol being removed more rapidly than any of its methylated homologues. Consequently, the alga was found to have a greater specificity for phenol than for o- or p-cresols. This study shows that O. danica could catabolize phenol and its methylated homologues.. ...

Detection of phenols using engineered bacteria. A biosensor can be created by placing a reporter gene under control of an inducible promoter. The reporter gene produces a signal when a cognate transcriptional activator senses the inducing chemical. Creation of bacterial biosensors is currently restricted by limited knowledge of the genetic systems of bacteria that catabolize xenobiotics. By using mutagenic PCR to change the chemical specificity of the Pseudomonas species CF600 DmpR protein, the potential for engineering novel biosensors for detection of phenols has been demonstrated. DmpR, a well-characterized transcriptional activator of the P. CF600s dmp operon mediates growth on simple phenols. Transcription from Po, the promoter heading the dmp operon, is activated when the sensor domain of DmpR interacts with phenol and mono-substituted phenols. By altering the sensor domain of the DmpR, a group of DmpR derivatives that activate transcription of a Po-lacZ fusion in response to eight of the EPAs

Phenols are among the highest-volume chemicals in production [ 3]. International organizations such as Agency for Toxic Substances and Disease Registry (ATSDR) [ 1] have documented phenol toxicity and recommend the monitoring of phenol exposure for groups at risk. The toxicity includes CNS depression and other symptoms such as skin burns, nausea, profuse sweating [ 1]. In exposure- and risk- evaluation, the monitoring of phenol by peripheral biomarker has several advantages over technical assessment of exposure. The urine methyl hippuric level is an acceptable peripheral biomarker for phenol exposure [ 1]. It was concluded that the phenol can be used for crude phenol exposure categorizations. Phenol is an important contamination in traffic fume [ 3]. High phenol exposure among the population living in the urban area of big city can be expected. Here, the author studied the urine phenol level among healthy subjects in urban area in Bangkok. We recommend that annual check up and monitoring for ...

The formation of aqueous bridges containing phenol and ethylene glycol as well as bisphenol-A, hydrochinone and p-cresol under the application of high voltage DC ("liquid bridges") is reported. Detailed studies were made for phenol and glycol with concentrations from 0.005 to 0.531 mol L−1. Conductivity as well as substance and mass transfers through these aqueous bridges are discussed and compared with pure water bridges. Previously suggested bidirectional mass transport is confirmed for the substances tested. Anodic oxidation happens more efficiently when phenol or glycol are transported from the cathode to the anode since in this case the formation of a passivation layer or electrode poisoning are retarded by the electrohydrodynamic (EHD) flow. The conductivity in the cathode beaker decreases in all experiments due to electrophoretic transport of naturally dissolved carbonate and bicarbonate to the anode. The observed electrochemical behavior is shortly discussed and compared to known ...

The final two steps in the dmp operon-encoded meta-cleavage pathway for phenol degradation in Pseudomonas sp. strain CF600 involve conversion of 4-hydroxy-2-ketovalerate to pyruvate and acetyl coenzyme A (acetyl-CoA) by the enzymes 4-hydroxy-2-ketovalerate aldolase and aldehyde dehydrogenase (acylating) [acetaldehyde:NAD+ oxidoreductase (CoA acetylating), EC 1.2.1.10]. A procedure for purifying these two enzyme activities to homogeneity is reported here. The two activities were found to copurify through five different chromatography steps and ammonium sulfate fractionation, resulting in a preparation that contained approximately equal proportions of two polypeptides with molecular masses of 35 and 40 kDa. Amino-terminal sequencing revealed that the first six amino acids of each polypeptide were those deduced from the previously determined nucleotide sequences of the corresponding dmp operon-encoded genes. The isolated complex had a native molecular mass of 148 kDa, which is consistent with the ...
Hello again,. Tori is unfortunately spending the night in the Primary Childrens Hospital ICU after an ambulance ride earlier today.... Still trying to ascertain her current respiratory issues but she has greatly improved since her arrival. Please keep her in your thoughts and prayers.. She was scheduled to finally have her spinal fusion tomorrow but alas those plans are squashed again.... Tori had her latest round of botox and phenol injections this past Thursday along with a Flu shot as well. Whitney, Brendan and Grandpa all have had a viral infection over the past several days as well and we believe that is what she has now caught. She produced a tremendous amount of secretions Saturday night and I had to suction her lungs out during the entire evening. She calmed down Sunday morning and we were planning on taking her to the PCMC for her pre-surgery blood work. But she was very lethargic and couldnt maintain a blood oxygen level above 80% with 8 liters of oxygen so we had to call 911 for ...
b. Functional inhibition of cells involved in physiopathological processes, such as platelet, responsible for thrombogenic events through the formation of thromboxane A2 via the cyclo-oxygenase pathway, and leukocytes, involved in inflammatory processes, through the formation of leukotrienes via the lipoxygenase pathway. In addition phenols modulate enzymes that regulate functions: the synthesis of nitric oxide (NO), a potent vasodilatator, by macrophages, is increased, while the production of the free radical anion superoxide, by the same type of cell, is reduced. In contrast, these activities are not shown by typical lipophilic antioxidants (e.g. Vitamin E). Phenols in olive oil share, therefore, a broad spectrum of biological activities, in addition to acting simply as antioxidants. This may be attributed to the chemical characteristics of these compounds, amphiphilic molecules, i.e. partly lipophilic with the typical lipid antioxidant activity (like Vitamin E) and partly hydrophilic, with ...

Biological degradation of phenol by Alcaligenes faecalis with high biodegradation activity and high tolerance was investigated at 25C. Phenol could be utilized by the bacteria as the sole carbon and energy sources. The cell growth and substrate degradation of phenol as single substrates for Alcaligenes faecalis in batch cultures (shaking flasks) were investigated at different initial phenol concentrations. Phenol was observed to be an inhibitory compound. Particularly, when free cells grew on a high concentration of phenol, substrate inhibition was observed and the higher the concentration of phenol, the longer was the lag period. The lag time and whole required time for phenol biodegradation was considerably decreased by immobilized cells due to improvement of cells resistance against high Phenol concentration by cell immobilization compared to free cells. Required time for completely degrade initial phenol of 700 and 1000 ppm by free and immobilized cells is 56, 101 and 35, 72 hours ...
Nickel was loaded onto hydrothermally-grown ZnO nanorods on cordierite substrates and tested as catalysts in microwave-enhanced degradation of phenol from its aqueous solution (100 ppm) at 70 degrees C. Effects of metal loadings (1, 10 and 20 mM impregnation solutions) on the degradation of phenol in aqueous solution was investigated. The catalyst performances were monitored based on phenol degradation, product distributions and carbon dioxide (CO2) evolutions. Based on the type of the catalysts, two different mechanistic pathways for the decomposition were observed-through catechol and/or hydroquinone as intermediates. It was found that the 10mM nickel loaded sample catalyzed the degradation through one pathway with hydroquinone as the benzenediol intermediate formed, while the 20 mM nickel impregnated sample catalyzed the reaction through two pathways, producing catechol as well as hydroquinone by products. These differences in reaction pathways were attributed to the variation in the ...

Degradation of aromatic hydrocarbons by aerobic bacteria is generally divided into an upper pathway, which produces dihydroxylated aromatic intermediates by the action of monooxygenases, and a lower pathway, which processes these intermediates down to molecules that enter the citric acid cycle. Bacterial multicomponent monooxygenases (BMMs) are a family of enzymes divided into six distinct groups. Most bacterial genomes code for only one BMM, but a few cases (3 out of 31) of genomes coding for more than a single monooxygenase have been found. One such case is the genome of Pseudomonas stutzeri OX1, in which two different monooxygenases have been found, phenol hydroxylase (PH) and toluene/o-xylene monooxygenase (ToMO). We have already demonstrated that ToMO is an oligomeric protein whose subunits transfer electrons from NADH to oxygen, which is eventually incorporated into the aromatic substrate. However, no molecular data are available on the structure and on the mechanism of action of PH. To ...
