| Abstract: | A mutant strain of Lipomyces kononenkoae 2896-3 synthesizing dextranase but resistant to catabolite repression was obtained using N-nitroso-N-methylurea treatment. Enzyme biosynthesis in media with dextran and other carbon sources was then characterized. The capacity of the mutant to produce dextranase when grown on hydrolysed corn starch is demonstrated. |
