The pattern of the vitamin B12 requirement of a soil bacterium "Lochhead 38" (provisionally assigned to Arthrobacter) resembled that of the protozoan Ochromonas malhamensis and of higher animals. Of the naturally-occurring B12-vitamins, cyanocobalamin and vitamin B12III are active. Pseudovitamin B12 and Factor A have very little or no intrinsic activity, and when present in relatively high concentrations both compounds depress the rate of the growth response to limiting cyanocobalamin. Factor B, the porphyrin-like nucleus of the vitamin B12 molecule without the nucleotide, is inactive, as are also methionine and deoxyribosides. A disadvantage in the use of Lochhead 38 for assay purposes is that in vitamin-B12-dehcient cultures the organisms flocculate.
