Abstract
The distribution of glycerol dehydrogenase activity was studied with cell-free extracts of bacteria, yeasts, molds and actinomycetes. High activity was found in 4 strains of bacteria and in 3 strains of molds. The enzymes of bacteria were dependent on NAD+ and those of molds were dependent on NADP+. An isolated gram-positive bacterium, which showed the high activity, was identified as Cellulomonas sp. NT3060. The total and specific activities were associated with growth of this strain and reached the maximum at the early stationary phase. Significant high level activity was detected in cell-free extracts from glycerol and glucose media.
