Notes:
Candida utilis CBS 621 contained four different enzymes capable of reducing carbonyl compounds such as dihydroxyacetone, acetoin, diacetyl, acetol, methylglyoxal and acetone, namely alcohol dehydrogenase, acetone reductase, dihydroxyacetone reductase and 2,3-butanediol dehydrogenase. The dihydroxyacetone reductase of C. utilis did not oxidize glycerol, thus providing evidence that this enzyme cannot function as a glycerol-2-dehydrogenase during growth of the yeast on glycerol. This enzyme may, however, play a role in the assimilation of 2,3-butanediol by C. utilis. The organism also contained a separate 2,3-butanediol dehydrogenase which was unable to reduce dihydroxyacetone. Both dihydroxyacetone reductase and 2,3-butanediol dehydrogenase were present at very high activities during growth of C. utilis on a variety of substrates, including 2,3-butanediol.
