FOERFARANDE FOER FRAMSTAELLNING AV CELLULOLYTISKA ENZYMER.

摘要

This invention concerns a process of producing cellulolytic enzymes by fermentation with the Trichoderma reesei fungus. This process includes two steps: (a) a first step of subjecting to aerobian fermentation a culture medium comprising a strain of Trichoderma reesei, nutrition compounds and a small quantity of cellulose and sugar, (b) a second step of contining the aerobian fermentation by adding soluble sugar at a speed such that the sugar concentration in the fermentation zone remains under 0.3% by weight. The cellulolytic enzymes obtained are used in the enzymatic hydrolysis of a lignocellulosic biomass.
