Twenty-seven yeasts were screened for starch breakdown; the three with the highest rate were strains of Filobasidium capsuligenum, Lipomyces starkeyi and Schwanniomyces occidentalis. Of these, only the last gave mutants with diminished carbon catabolite repression and, hence, enhanced amylase activi

A catabolite repression-insensitive mutant of Candida boidiniiA5, strain ADU-15, was investigated as to alcohol oxidase production and the production of cells exhibiting the maximum catalytic activity for formaldehyde production. The mutant strain ADU-15 showed higher cell productivity and higher al
Mutants with defective carbon catabolite repression have been isolated in the yeast Saccharomyces cerevisiae using a selective procedure. This was based on the fact that invertase is a glucose repressible cell wall enzyme which slowly hydrolyses raffinose to yield fructose and that the inhibitory ef
