Conversion of benzoic acid to benzoic acid dihydrodiol by the benzoate 1,2-dioxygenase subunits A, B and C (BenABC) while the benzoate 1,2-dioxygenase subunit D (BenD) further catalyzes the reaction of benzoic acid dihydrodiol to catechol. 2. Anaerobic conversion of benzoic acid to benzoyl-...
Benzoic acid and sodium benzoate are commonly used food preservative. In acidic conditions, it has inhibitory effect on yeast and mold. When pH value is 3 antibacterial strength, when pH was 6 for a lot of mould effect is very poor, so the inhibition the optimum pH value is 2.5-4.0. In...
