Abstract

Abstract We isolated stable mutants from Trichosporon adeninovorans resistant to 2‐deoxy‐D‐glucose. All mutants were altered in the C‐catabolite repression and produced different amounts of glucoamylase and β‐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.
