Abstract Candida transglucosyl-amylase (Sawai, 1958, 1960; Sawai and Hehre, 1962) was found to be produced intracellularly by three of 28 species within theCandida genus, i.e. by 29 of 35C. tropicalis strains, all of 15C. albicans strains and oneC. claussenii. The novel capacity of this enzyme to catalyze transglucosylation from starch was substantiated by the observation that preparations from all the positive strains were highly effective in causing such transfer to glycerol, and by the fact that isomaltose was synthesized from dextrin by the action of all preparations checked for this capacity (21 strains). Two strains ofC. pelliculosa produced an amylase of a different kind, while representatives of the remaining 24Candida species tested (one or two strains of each species) gave no evidence of amylase production. In view of the narrow and apparently specific distribution of transglucosyl-amylase within the genus, it seems possible that production of this enzyme might be useful as an aid in the taxonomic differentiation ofCandida yeasts.
