A kinetic study on benzoic acid pungency and sensory attributes of benzoic acid. (1/279)

Aqueous solutions of benzoic acid (BA) were evaluated by two methods: (i) sensory profile: a descriptive test of sensory attributes combined with semiquantitative analysis; and (ii) pungency intensity measures as a function of time: a computerized recording using specific software. Kinetic parameters evaluated were maximal intensity (I(MAX)), total time of pungency (Ttot), rates of increase (V1) and decrease (V2), half-life (T1/2), area under curve (AUC) and time to maximal intensity (T(IMAX)). Results were analyzed by ANOVA, LSD test, iterative calculations and adjustment to equations according to mathematical models, regression analysis, principal component analysis (PCA) and clusters analysis. Pungency was the main sensory attribute of BA (3-36 mM) in the tongue and epiglottis. The seven kinetic parameters showed concentration-dependency (P < 0.001) and were described by different functions: (i) lineal: I(MAX) = 2.24 +/- 0.14C - 3.06 +/- 2.58, R2 = 0.98; T(IMAX) = 0.19 +/- 0.02C + 6.87 +/- 0.47, R2 = 0.92; V1 = 0.68 +/- 0.03C + 0.10 +/- 0.69, R2 = 0.99; AUC = 49.10 +/- 3.17C - 230.78 +/- 59.66, R2 = 0.98; (ii) potency: T1/2 = 6.62 +/- 0.61C(0.39+/-0.03), R2 = 0.97; V2 = 1.07 +/- 0.11C(0.53+/-0.04), R2 = 0.98; Ttot = 8.08 +/- 1.01C(0.43+/-0.04), R2 = 0.96. PCA revealed high correlation between (i) T(IMAX) and Ttot; (ii) T1/2 and V2; and (iii) I(MAX) and V1. Stimuli grouped across three main clusters: (i) 3 and 6 mM; (ii) 9, 12 and 18 mM; and (iii) 24 and 36 mM. Maximal pungency intensity best correlated with both concentration and persistence among kinetic parameters. Prototypical prickling of BA was observed at 12 and 18 mM.  (+info)

Chemicals in laboratory room air stimulate olfactory neurons of female Bombyx mori. (2/279)

Laboratory air contained odorants that elicited electrophysiological responses in female Bombyx mori antennae. Air entrainments on charcoal filters, extracted with CS(2) and subsequently with acetone, were analyzed by coupled gas chromatography (GC)-electroantennogram (EAG) as well as by GC-mass spectrometry. The CS(2) extract contained 12 EAG-active peaks from which benzaldehyde, octanal, limonene, 1,8-cineol, methyl benzoate, nonanal, decanal and geranyl acetone were identified. In the acetone extract we identified eight EAG-active peaks as phenol, nonanal, 2-ethylhexanoic acid, octanoic acid, benzoic acid, nonanoic acid, decanoic acid and dimethyl phthalate. The concentrations of benzoic acid and benzaldehyde present in laboratory air were determined. The origin of the substances and importance of such odorants in laboratory air for the interpretation of physiological experiments on the olfactory system is discussed.  (+info)

Gene cloning and nucleotide sequencing and properties of a cocaine esterase from Rhodococcus sp. strain MB1. (3/279)

A strain of Rhodococcus designated MB1, which was capable of utilizing cocaine as a sole source of carbon and nitrogen for growth, was isolated from rhizosphere soil of the tropane alkaloid-producing plant Erythroxylum coca. A cocaine esterase was found to initiate degradation of cocaine, which was hydrolyzed to ecgonine methyl ester and benzoate; both of these esterolytic products were further metabolized by Rhodococcus sp. strain MB1. The structural gene encoding a cocaine esterase, designated cocE, was cloned from Rhodococcus sp. strain MB1 genomic libraries by screening recombinant strains of Rhodococcus erythropolis CW25 for growth on cocaine. The nucleotide sequence of cocE corresponded to an open reading frame of 1,724 bp that codes for a protein of 574 amino acids. The amino acid sequence of cocaine esterase has a region of similarity with the active serine consensus of X-prolyl dipeptidyl aminopeptidases, suggesting that the cocaine esterase is a serine esterase. The cocE coding sequence was subcloned into the pCFX1 expression plasmid and expressed in Escherichia coli. The recombinant cocaine esterase was purified to apparent homogeneity and was found to be monomeric, with an M(r) of approximately 65,000. The apparent K(m) of the enzyme (mean +/- standard deviation) for cocaine was measured as 1.33 +/- 0.085 mM. These findings are of potential use in the development of a linked assay for the detection of illicit cocaine.  (+info)

A 90-kilobase conjugative chromosomal element coding for biphenyl and salicylate catabolism in Pseudomonas putida KF715. (4/279)

The biphenyl and salicylate metabolic pathways in Pseudomonas putida KF715 are chromosomally encoded. The bph gene cluster coding for the conversion of biphenyl to benzoic acid and the sal gene cluster coding for the salicylate meta-pathway were obtained from the KF715 genomic cosmid libraries. These two gene clusters were separated by 10-kb DNA and were highly prone to deletion when KF715 was grown in nutrient medium. Two types of deletions took place at the region including only the bph genes (ca. 40 kb) or at the region including both the bph and sal genes (ca. 70 kb). A 90-kb DNA region, including both the bph and sal genes (termed the bph-sal element), was transferred by conjugation from KF715 to P. putida AC30. Such transconjugants gained the ability to grow on biphenyl and salicylate as the sole sources of carbon. The bph and sal element was located on the chromosome of the recipient. The bph-sal element in strain AC30 was also highly prone to deletion; however, it could be mobilized to the chromosome of P. putida KT2440 and the two deletion mutants of KF715.  (+info)

Novel scheme for biosynthesis of aryl metabolites from L-phenylalanine in the fungus Bjerkandera adusta. (5/279)

Aryl metabolite biosynthesis was studied in the white rot fungus Bjerkandera adusta cultivated in a liquid medium supplemented with L-phenylalanine. Aromatic compounds were analyzed by gas chromatography-mass spectrometry following addition of labelled precursors ((14)C- and (13)C-labelled L-phenylalanine), which did not interfere with fungal metabolism. The major aromatic compounds identified were benzyl alcohol, benzaldehyde (bitter almond aroma), and benzoic acid. Hydroxy- and methoxybenzylic compounds (alcohols, aldehydes, and acids) were also found in fungal cultures. Intracellular enzymatic activities (phenylalanine ammonia lyase, aryl-alcohol oxidase, aryl-alcohol dehydrogenase, aryl-aldehyde dehydrogenase, lignin peroxidase) and extracellular enzymatic activities (aryl-alcohol oxidase, lignin peroxidase), as well as aromatic compounds, were detected in B. adusta cultures. Metabolite formation required de novo protein biosynthesis. Our results show that L-phenylalanine was deaminated to trans-cinnamic acid by a phenylalanine ammonia lyase and trans-cinnamic acid was in turn converted to aromatic acids (phenylpyruvic, phenylacetic, mandelic, and benzoylformic acids); benzaldehyde was a metabolic intermediate. These acids were transformed into benzaldehyde, benzyl alcohol, and benzoic acid. Our findings support the hypothesis that all of these compounds are intermediates in the biosynthetic pathway from L-phenylalanine to aryl metabolites. Additionally, trans-cinnamic acid can also be transformed via beta-oxidation to benzoic acid. This was confirmed by the presence of acetophenone as a beta-oxidation degradation intermediate. To our knowledge, this is the first time that a beta-oxidation sequence leading to benzoic acid synthesis has been found in a white rot fungus. A novel metabolic scheme for biosynthesis of aryl metabolites from L-phenylalanine is proposed.  (+info)

Developmental regulation of methyl benzoate biosynthesis and emission in snapdragon flowers. (6/279)

In snapdragon flowers, the volatile ester methyl benzoate is the most abundant scent compound. It is synthesized by and emitted from only the upper and lower lobes of petals, where pollinators (bumblebees) come in contact with the flower. Emission of methyl benzoate occurs in a rhythmic manner, with maximum emission during the day, which correlates with pollinator activity. A novel S-adenosyl-l-methionine:benzoic acid carboxyl methyl transferase (BAMT), the final enzyme in the biosynthesis of methyl benzoate, and its corresponding cDNA have been isolated and characterized. The complete amino acid sequence of the BAMT protein has only low levels of sequence similarity to other previously characterized proteins, including plant O-methyl transferases. During the life span of the flower, the levels of methyl benzoate emission, BAMT activity, BAMT gene expression, and the amounts of BAMT protein and benzoic acid are developmentally and differentially regulated. Linear regression analysis revealed that production of methyl benzoate is regulated by the amount of benzoic acid and the amount of BAMT protein, which in turn is regulated at the transcriptional level.  (+info)

Allosteric inhibition of endothelin ETA receptors by 3, 5-dibromosalicylic acid. (7/279)

Derivatives of salicylic acid (SA) and benzoic acid prevent endothelin-1 (ET-1) binding to ETA receptors. This study analyzed actions of 30 derivatives of benzoic acid and salicylic acid on (125)I-ET-1 binding to recombinant rat ETA receptors. The most active compounds were 3,5-dibromosalicylic acid (Br2SA, K(i) = 0.5 mM) and 3,5-diiodosalicylic acid (K(i) = 0.3 mM). They were about 50 times more potent than SA and aspirin. Br2SA inhibited equilibrium (125)I-ET-1 binding in an apparently competitive manner. It accelerated 8-fold the dissociation of (125)I-ET-1 receptor complexes and did not modify the second order rate constant of association of (125)I-ET-1 to its receptors. Br2SA also decreased the affinity of ETA receptors for receptor antagonists BQ-123 and bosentan. Br2SA accelerated dissociation of (125)I-ET-1-solubilized ETA receptor complexes and decreased the apparent molecular size of solubilized receptors. Br2SA and 3,5-diiodosalicylic acid inhibited two cellular actions of ET-1: the mobilization of intracellular Ca(2+) stores in isolated cells and contractions of rat aortic rings. They accelerated the relaxing action of BQ-123 and bosentan in ET-1-treated aortic rings. The results suggest the existence of an allosteric modifier site on ETA receptors that recognizes selected derivatives of SA. SA derivatives might be of therapeutic interest to relieve tight ET-1 binding and to favor actions of receptor antagonists.  (+info)

Genetic manipulation of 6-phosphofructo-1-kinase and fructose 2,6-bisphosphate levels affects the extent to which benzoic acid inhibits the growth of Saccharomyces cerevisiae. (8/279)

The mechanisms by which the weak acid preservative benzoic acid inhibits the growth of Saccharomyces cerevisiae have been investigated. A reduction in the pyruvate kinase level, which decreases glycolytic flux, did not increase the sensitivity of yeast to benzoic acid. However, a decrease in 6-phosphofructo-1-kinase (PF1K), which does not affect glycolytic flux, did increase sensitivity to benzoic acid. Also, resistance was increased by elevating PF1K levels. Hence, resistance to benzoic acid was not dependent upon optimum glycolytic flux, but upon an adequate PF1K activity. Benzoic acid was shown to depress fructose 2,6-bisphosphate levels in YKC14, a mutant with low PF1K levels. This effect was partially suppressed by overexpressing constitutively active 6-phosphofructo-2-kinase (Pfk26(Asp644)) or by inactivating fructose-2,6-bisphosphatase (in a Deltafbp26 mutant). The inactivation of PF2K (in a Deltapfk26 Deltapfk27 mutant) increased benzoic acid sensitivity. Therefore, the antimicrobial effects of benzoic acid can be relieved, at least in part, by the genetic manipulation of PF1K or fructose 2,6-bisphosphate levels.  (+info)

Benzoic acid and its salts are used as a food preservatives, represented by the E numbers E210, E211, E212, and E213. Benzoic acid inhibits the growth of mold, yeast[24] and some bacteria. It is either added directly or created from reactions with its sodium, potassium, or calcium salt. The mechanism starts with the absorption of benzoic acid into the cell. If the intracellular pH changes to 5 or lower, the anaerobic fermentation of glucose through phosphofructokinase is decreased by 95%. The efficacy of benzoic acid and benzoate is thus dependent on the pH of the food.[25] Acidic food and beverage like fruit juice (citric acid), sparkling drinks (carbon dioxide), soft drinks (phosphoric acid), pickles (vinegar) or other acidified food are preserved with benzoic acid and benzoates.. Typical levels of use for benzoic acid as a preservative in food are between 0.05-0.1%. Foods in which benzoic acid may be used and maximum levels for its application are controlled by local food ...

Metabolism Information for Isodecyl Benzoate Isodecyl Benzoate (IDB) is an alkyl benzyl ester, also referred to as a carboxylic ester (R-C(O)-OR) produced by reaction with benzoic acid and isodecyl (C10) alcohol. An important feature is that such esters are poorly soluble in water. Esters are reactive with water and can hydrolyze under either acidic or basic conditions. The expected hydrolysis of IDB would be a reverse of the esterification process (generally catalyzed with esterase) and would produce benzoic acid and primary C10 alcohol. Benzoic acid can be further metabolised to hippuric acid and benzoyl glucuronide and excreted in the urine. Some benzoic acid may also be excreted in the urine. The primary C10 alcoholcan be further metabolised by mitochondrial beta-oxidation or by cytochrome P450 mediated omega and omega-minus-one oxidation (may be followed by beta-oxidation). The C10 alcohol can undergo various oxidative steps to yield other smaller alcohols, ketones, aldehydes, or ...

In the present study, FCR was improved by benzoic acid supplementation in the starter and finisher period. Better feed conversion of broiler chickens in the early stage of growth might be associated with the bacteriostatic effect of benzoic acid and less competition for nutrients between host and native microbiota. It has been shown that benzoic acid has antimicrobial properties, mainly because of its inhibitory effect on several microbial enzymes, in particular, a-ketoglutaric acid dehydrogenase and succinic acid dehydrogenase (Bosund, 1962). Knarreborg et al. (2002) demonstrated, in the batch culture conditions, that the benzoic acid and, to a lesser extent, fumaric acid exerted strong lethal properties towards lactic acid bacteria. The above authors suggested pH-dependent effects on coliform bacteria and lactic acid bacteria in stomach content and on coliform bacteria in content from the small intestine. The pH values used in the batch culture system by (Knarreborg et al., 2002) were supposed ...

A theoretical study supported by some experimental tests has been carried out with the aim of comparing one-dimensional (1-D) biofilm reactor models that use simplified (zero- and first-order) and Monod kinetics. Two different situations have been compared: one rate-limiting substrate with or without liquid film diffusion. The results obtained show that the use of a simplified kinetic approach compared to the Monod kinetic approach determines (1) an unjustified overestimate of the removal rate, especially for thin biofilms, and (2) an excessive overestimate of the liquid film layer thickness necessary to justify high kinetic orders. Even if recent research projects show that biofilm structure is more complicated than the one assumed in the modelling approach used in this study, nevertheless 1-D models still now continue to be the only ones that can reasonably support process engineers in biofilm reactor design, due to their intrinsic simplicity and the need for small sets of input data and ...

Under some conditions, a first-order kinetic model is a poor representation of biodegradation in contaminated aquifers. Although it is well known that the assumption of first-order kinetics is valid only when substrate concentration, S, is much less than the half-saturation constant, K(s), this assumption is often made without verification of this condition. We present a formal error analysis showing that the relative error in the first-order approximation is S/K(S) and in the zero-order approximation the error is K(s)/S. We then examine the problems that arise when the first-order approximation is used outside the range for which it is valid. A series of numerical simulations comparing results of first- and zero-order rate approximations to Monod kinetics for a real data set illustrates that if concentrations observed in the field are higher than K(s), it may better to model degradation using a zero-order rate expression. Compared with Monod kinetics, extrapolation of a...

ABSTRACT. The present work attempts to solve pollution problems in watery surroundings by aromatic compounds such as the phenol and the benzoic acid. Several ways of elimination of these compounds were the object of different research among which is the use of bacteria. In this framework, Pseudomonas aeruginosa bacterium is used to eliminate phenol and the benzoic acid. This made it possible to isolate the Pseudomonas aeruginosa bacterium directly on the nourishing environment containing phenol and benzoic acid as source of energy then the bacteria is incubated at 37˚C during a minimal duration of four days. Furthermore, we studied the influence of the Pseudomonas aeruginosa bacterium on the deterioration of an area exposed to a phenol and the benzoic acid concentration. Results obtained at the time of the different experimentations clearly show that phenol and the benzoic acid were eliminated by the Pseudomonas aeruginosa bacterium. However, it was noted that during the various investigations ...

The levels of preservatives are regulated in processed food - not that its a good idea to eat them. Sodium benzoate, for example, is included at ~0.1% in foods that contain it - hence, a liter of soup contains a milliliter (1 cc) of sodium benzoate. While no sane person would knowingly eat a teaspoon of a benzoic acid derivative, since it kills microbes theyve allowed it in food.. If most of your food has preservatives in it (i.e. if it is typical processed food or soft drinks, engineered for long shelf life), then you could be ingesting say, 50 grams of chemical preservatives a month. The food industry says it is safe based on ancient studies done in the 1950s, but thats not so very clear. In the end, compounds like benzoic acid (benzene + CO2 -> benzoic acid) have to be eliminated by the liver, and too much leads to toxic effects, like damage to ...

Dr. Clarks response - Sodium benzoate works by pulling ammonia out of the body. Ammonia is converted to urea for excretion in the urine by going through the urea cycle. The urea cycle starts when ammonia is converted to carbamyl phosphate. Carbamyl phosphate commits the body to making urea. The VERY next reaction consumes ornithine. So when sodium benzoate is given to the GAMT patients the thinking is it is sparing the loss of ornithine by the urea cycle. If ornithine is not consumed by the urea cycle maybe it can stay around to inhibit AGAT. That is the theory. Sodium Benzoate has a long history for treating patients with urea cycle deficits and is generally considered to be safe. It is actually found in some foods as a preservative. Based on its safety and the importance of sparing ornithine I do think the sodium benzoate is a good option for GAMT patients. I think some physicians may be hesitant to use it in GAMT patients because usually sodium benzoate is indicated to decrease ammonia, and ...

As a followup to the earlier Bateman (2004) study, the authors retested a 153 toddlers as well as 144 elementary school (8/9 years old) children from the general population. They were briefly put on a dye-free diet and then tested with a modest amount (20 mg and 30 mg) of food dyes mixed with the sodium benzoate preservative.. AUTHORS CONCLUSION: Artificial colours or a sodium benzoate preservative (or both) in the diet result in increased hyperactivity in 3-year-old and 8/9-year-old children in the general population.. NOTE: These children were not hyperactive, nor were they screened for sensitivity to the dyes or any other additives. Nevertheless, they showed more hyperactive-type behaviors when consuming the combination of food dyes and the preservative.. NOTE: I have always wondered why this study uses sodium benzoate rather than the BHT, BHA, and TBHQ that saturates so much of American food. The Feingold diet doesnt eliminate sodium benzoate and most (but not all) members tolerate it. ...

Neuraminidase (NA), a surface glycoprotein of influenza virus, is a potential target for design of antiinfluenza agents. The crystal structure of influenza virus neuraminidase showed that in the active site 11 residues are universally conserved among all strains known so far. Several potent inhibitors based on the carbohydrate compound 2-deoxy-2,3-didehydro-D-N-acetylneuraminic acid (DANA) have been shown to bind to the conserved active site and to reduce virus infection in animals when administered by nasal spray. Inhibitors of this type are, however, rapidly excreted from physiological systems and may not be effective in order to provide long-time protection. A new class of specific NA inhibitors, which are benzoic acid derivatives, has been designed on the basis of the three-dimensional structure of the NA-DANA complex and modeling of derivatives of 4-(acetylamino)benzoic acid in the NA active site. Intermediates were synthesized and were shown to moderately inhibit the NA activity and to ...
