Synthesis of Exopolysaccharide by Bradyrhizobium japonicum during Growth on Hydroaromatic Substrates.

abstract：:The decarboxylation of phthalic acids was studied with Bacillus sp. strain FO, a marine mixed culture ON-7, and Pseudomonas testosteroni. The mixed culture ON-7, when grown anaerobically on phthalate but incubated aerobically with chloramphenicol, quantitatively converted phthalic acid to benzoic acid. Substituted pht...
