The Production of α-Ketoglutaric Acid form Salicylic Acid by Pseudomonas sp.

Abstract

Metabolites from salicylic acid by microorganisms were investigated. About eighty strains of bacteria which were able to utilize salicylic acid as a sole source of carbon were isolated from soil and other natural sources.
Among these bacteria, several strains produced a large amount of keto acids in the culture fluid during the cultivation. The acid was isolated from the culture fluid of strain K 102 in crystalline form. The crystal was identified as α-ketoglutaric acid by physicochemical methods. From the taxonomical studies, the isolated bacterial strains K 102 and K 362 were assumed to be Pseudomonas sp.
