Mutants of Candida wickerhamii and Dekkera intermedia , derepressed for β‐glucosidase biosynthesis, were isolated. These mutants were also shown to hyperproduce this enzyme. In anaerobic culture, the C. wickerhamii mutant still hyperproduced β‐glucosidase and was derepressed. Glucose‐cellobiose anaerobic fermentation by this strain was thus improved. On the other hand, the D. intermedia mutant did not show any difference from the wild‐type strain in anaerobic culture.
