Certain Mycobacteriu form adaptive enzymes for the oxidation of benzoic acid (1). The oxidation proceeds through catechol and protocatechuic acid (2) and is thus similar to that in PseudomonasJEuorescens (3). Neither cyclohexanecarboxylic acid nor any substituted benzoic acid is oxidized by these Mycobacteria, but certain of these compounds can induce the organism to form adaptive enzymes for b...

Pyridinium-grafted-cellulose nanocrystals were prepared by a simple one-pot reaction using 4-(1-bromoethyl/bromomethyl)benzoic acid, pyridine and cellulose nanocrystals (CNCs). The grafting consists of an esterification reaction between 4-(1-bromoethyl/bromomethyl)benzoic acid and CNCs and a nucleophilic attack on the C-Br bond of 4-(1-bromoethyl/bromomethyl)benzoic acid by pyridine. This react...

This article deals with the study of antiwear and antifriction properties of bitter rapeseed oil and sesame oil and their blends containing numerous amounts of benzoic acid at variable temperatures. The experimental results indicate that bitter rapeseed oil exhibits good antiwear and antifriction properties as compared to sesame oil under the same experimental conditions. The addition of benzoi...

Benzoic acid and some related compounds are able to increase the metabolism of mycobacteria (Bernheim, 1941). The oxygen uptake and carbon dioxide production of the pathogenic strains H-37 and B, are greatly accelerated when small amounts of benzoic or salicylic (o-hydroxybenzoic) acid are added to the bacterial suspensions. Other hydroxybenzoic acids as well as aminobenzoic acids are without e...

There are many difficulties in the purification of raw components and products. However, researchers are seeking better ways for purification. One of the recent methods is extraction using supercritical fluids. In this study, the phase equilibria of benzoic acid -supercritical carbon dioxide system were investigated. Regarding the phase equilibria of this system, the modeling of solid-supercrit...

Infections related to Aspergillus species have emerged to become an important focus in infectious diseases, as a result of the increasing use of immunosuppressive agents and high fatality associated with invasive aspergillosis. However, laboratory diagnosis of Aspergillus infections remains difficult. In this study, by comparing the metabolomic profiles of the culture supernatants of 30 strains...

Benzoic acid is occasionally used as a raw material supplement in food products and is sometimes generated during the fermentation process. In this study, the production of naturally occurring yogurt preservatives was investigated for various starter cultures and incubation temperatures, and considered food regulations. Streptococcus thermophilus, Lactobacillus acidophilus, Lactobacillus delbru...

In general, creation of superhydrophobic surfaces is composed of two steps: (i) creation of a rough surface and (ii) passivation of the surface with the low surface energy molecules or coatings. Superhydrophobic properties cannot be achieved on a surface without these two essential factors fulfilled. In the present work we have demonstrated that superhydrophobic silver films on copper (Cu) subs...

The specific set of reactions that lead to the synthesis of benzoic acid in plants is still unclear, and even the subcellular compartment in which these reactions occur is unknown. Biosynthesis of both vegetative tissues and seeds of Arabidopsis thaliana contain a class of defense compounds termed glucosinolates, but only the seeds synthesize and store high levels of two glucosinolate compounds...

The monolayer-forming, human choriocarcinoma cell line, BeWo, was used to study the mechanisms of monocarboxylic acid transport across the human trophoblast. Benzoic acid, acetic acid, and lactic acid were used as markers for monocarboxylic acid carrier-mediated transport. The uptake of benzoic acid by BeWo cells was saturable (K(t) = 0.6 +/- 0.3 mM) at higher concentrations and significantly i...
