Abstract
Summary
1. Resting cells of A. suboxydans, grown with deficient levels of pantothenic acid, were investigated for their ability to oxidize a series of substrates. These cells showed retarded ability to oxidize dihydroxyacetone, sorbose, and gluconic acid, and somewhat poorer ability to convert sorbitol to sorbose. 2. Addition of coenzyme A to the deficient cells significantly improved their ability to oxidize dihydr oxy ace tone, thus suggesting that the further dissimilation of this substrate is coenzyme A-linked. 3. The oxidation of alcohol, of glycerol to dihydroxyacetone, and of glucose to gluconic acid proceeded with equal velocity in deficient and normal cells, indicating non-involvement of coenzyme A in these reactions.
