The effect of sodium benzoate on the quality attributes of improved tamarind beverage during storage was investigated. Tamarind beverages were produced according to a previously reported improved method, with or without chemical preservatives (100 mg/100 mL sodium benzoate). Tamarind beverage produced according to traditional processing method served as the control. The tamarind beverages were ...

The metabolism of benzoate, cyclohex-1-ene carboxylate, and cyclohexane carboxylate by "Syntrophus aciditrophicus" in cocultures with hydrogen-using microorganisms was studied. Cyclohexane carboxylate, cyclohex-1-ene carboxylate, pimelate, and glutarate (or their coenzyme A [CoA] derivatives) transiently accumulated during growth with benzoate. Identification was based on comparison of retentio...

During batch growth of Ralstonia eutropha (previously named Alcaligenes eutrophus) on phenol in the presence of acetate, acetate was found to be the preferred substrate; this organic acid was rapidly metabolized, and the specific rate of phenol consumption was considerably decreased, although phenol consumption was not abolished. This decrease corresponded to a drop in phenol hydroxylase and ca...

Guest molecules in layered double hydroxides (LDHs) may be located both on the surface and interlayer gallery. In this work, a comparative study of various IR spectroscopic methods coupled with X-ray diffraction (XRD) is presented, which makes it possible to distinguish between two possibilities. During experimental first, CaAl-LDHs intercalated nitrate/carbonate ions were transformed d-glucona...

A systematic study on the influence of functionality on adsorption of benzoate and phthalate at -alumina–water interface was investigated. Kinetics of adsorption of benzoate and phthalate on -alumina surfaces were performed at constant ionic strength, I= 5× 10−4 mol dm−3 and pH 5 at 25, 30 and 40 ◦C. Kinetics results show that the rate of adsorption of phthalate is ≈2 times more than that of be...

BACKGROUND In an effort to identify alternate recombinant gene expression systems in Pseudomonas fluorescens, we identified genes encoding two native metabolic pathways that were inducible with inexpensive compounds: the anthranilate operon (antABC) and the benzoate operon (benABCD). RESULTS The antABC and benABCD operons were identified by homology to the Acinetobacter sp. anthranilate opero...

The crystal structure of the title compound (4CP4MBA), C(14)H(11)ClO(2), resembles those of 3-chloro-phenyl 4-methyl-benzoate (3CP4MBA), 4-methyl-phenyl 4-methyl-benzoate (4MP4MBA), 4-methyl-phenyl 4-chloro-benzoate (4MP4CBA) and other aryl benzoates with similar bond parameters. The dihedral angle between the benzene rings in 4CP4MBA is 63.89 (8)°, compared with 71.75 (7)° in 3CP4MBA, 63.57 (5...

The structure of the title compound (4CP4CBA), C(13)H(8)Cl(2)O(2), resembles those of 4-methyl-phenyl 4-chloro-benzoate (4MP4CBA), 4-chloro-phenyl 4-methyl-benzoate (4CP4MBA) and 4-methyl-phenyl 4-methyl-benzoate (4MP4MBA), with similar bond parameters. The dihedral angle between the two benzene rings in 4CP4CBA is 47.98 (7)°, compared with 51.86 (4)° in 4MP4CBA, 63.89 (8)° in 4CP4MBA and 63.57...

We report the first case of an anaphylactic reaction to Reandron 1000 (depot testosterone undecanoate with a castor oil and benzyl benzoate vehicle). While considered to have a favourable safety profile, serious complications such as oil embolism and anaphylaxis can occur. In our patient, skin testing identified benzyl benzoate to be the trigger, with no reaction to castor oil or testosterone u...
