Modified strains of Trichoderma reesei having cellulase promoters with xylase gene promoting sequences

摘要

The invention relates to strains of Trichoderma reesei wherein the inducibility of the promoters of the cellulase genes is modified. The expression of cellulases by these strains of T. reesei is induced by the presence of an inducing substrate, said inducing substrate exerting no or little inducing effect on the non-modified strain of T. reesei, while keeping inducibility of the cellulases by their inducing substrate.
