Beschreibung
Zusammenfassung:This specification discloses a process for producing at least one enzyme from a host cell for the hydrolysis of a first pre-treated ligno-cellulosic biomass under simple sugar starved conditions wherein the cultivation environment has very little, preferable no, simple sugars added other than those present in a ligno-cellulosic biomass used to feed and grow the host cell. The cultivation environment is substantially void of fermentation stimulators and inducers of enzyme production. Preferably, the cultivation environment has a high dry matter content of the pre-treated ligno-cellulosic biomass.
