✦ Synopsis

We isolated stable mutants from Trichosporon adeninovorans resistant to 2-deoxy-~-glucose. All mutants were altered in the C-catabolite repression and produced different amounts of glucoamylase and 8-glucosidase when grown on several carbon sources. In addition to the C-catabolite derepression of these extracellular enzymes, a repression defect .of isocitrate lyase was found.

Several yeast species have been investigated as potentially valuable candidates for the production of single cell protein or ethanol from starch. Therefore, in various laboratories extracellular amylolytic enzymes of yeasts have become subject of study (CLEMENTI et al.
