PROCESS FOR THE PRODUCTION OF PROTEINS, SUGARS, ALCOHOL, BY A STRAIN OF TRICHODERMA MUSHROOM IN WHICH THE CEL1A GENE IS INVALID

摘要

The invention relates to the various uses of a fungus strain belonging to the genus Trichoderma in which the cel1a gene is invalidated. The present invention relates in particular to a process for the production of proteins by a strain of fungus belonging to the Trichoderma genus in which the cel1a gene is invalidated, comprising at least two steps: - a first batch phase growth step in the presence of at least one carbonaceous growth substrate, and- a second step of producing fed-batch phase proteins in the presence of a composition comprising at least lactose and a second sugar, the lactose content in said composition representing approximately between 5 and 30% by weight of the total sugar content in said composition.
