A screening test was performed with about 240 samples of soil and sewgas collected from various parts of Aichi Prefecture in order to obtain bacteria which can produce a large amount of α-ketoglutaric acid (α-KG) in a culture fluid. As a result of the test, 4 strains of bacteria with the highest productivity, of α-KG 53D, 190C, 190D and 170D, were isolated.From a culture filtrate of 190C pure α-KG was extracted and identified.These 4 strains were identified taxonomically according to Bergey's Manual of Determinative Bacteriology, 7th edition, and the following conclusions were obtained : 190C should be identified as a veriety of Pseudomonas fluorescens and 190D as that of Ps. ovalis. 53D also belongs to genus Pseudomonas and was closely related to aeruginosa though no aeruginosa species coincided exactly with 53D. 170D should fall within genus Achromobacter but there are no known Achromobacter species which are perfectly identical with it.
