For Hypocrea jecorina (anamorph Trichoderma reesei), a filamentous fungus used for hydrolase production in different industries, it has been a long-term practice to use d-xylose as an inducing substance. We demonstrate in this study that the degree of xylanase-encoding gene induction strictly depends on the concentration of d-xylose, which was found to be optimal from 0.5 to 1 mM for 3 h of cultivation. At higher concentrations of d-xylose, a reduced level of xylanase gene expression was… CONTINUE READING
