The filamentous fungus Penicillium italicum produced a certain level of beta-1,3-glucanase during active growth in a glucose-supplemented medium; however, at a low glucose concentration (2 to 10 mM), derepression took place and the specific activity of the enzyme increased significantly. Derepressed cells (incubated in a glucose-limited medium) accumulated a capacity for the synthesis of beta-1,3-glucanase, which led to a subsequent increase in the specific activity even when the cells were… CONTINUE READING
