Cell suspensions of A. mycoides oxidized glucose, fructose, and mannose. Glucose, pyruvate, lactate, and, in the presence of catalase, glycerol were oxidized quantitatively to acetate and carbon dioxide. Anaerobically, pyruvate underwent dismutation to acetate, lactate, and carbon dioxide. Neither glucose nor glycerol were attacked anaerobically by intact cell suspensions. No other pentoses, hexoses, di-, tri-, or polysaccharides, or polyhydric alcohols, were attacked by cells grown in a complex undefined medium.

Strains of Mycopiasma mycoides subsp. mycoides have been divided into small colony (SC) and large colony (LC) types (Cottew & Yeats, 1978). The protein patterns of representative strains of these two types and of M . mycoides subsp. Capri were compared by a high resolution, two-dimensional gel electrophoretic method. The results suggest that the LC strains are more closely related to M . mycoides subsp. Capri than to the SC strains of M. mycoides subsp. mycoides.

Cell suspensions of A. mycoides oxidize glucose but do not attack it anaerobically. The pathway for glucose oxidation was investigated.
