S ummary . The ability of 6 Gram negative, yellow pigmented rods to metabolize various amino compounds was investigated. The strains examined represented 3 groups of organisms of this type. The strains of 2 groups, O and S, had low G+C ratios while those of group Y had high G+C ratios. Strains of groups O and S dissimilated arginine by the dihydrolase pathway but the group Y organisms did not attack arginine. No decarb‐oxylase activity was recorded, but the ability to transaminate amino acids in the presence of added keto acids was demonstrated for all the strains examined. The pattern of amino acid degradation produced by strains of the low G+C groups was similar though distinct from that of the high G+C types. In the absence of added keto acids deamination was the main mode of attack on amino compounds.
