Abstract
The present invention relates to a method of producing cellulolytic and/or hemicellulolytic enzymes by a cellulolytic microorganism in a stirred and aerated bioreactor, comprising a growth stage in the presence of a carbon source and a production stage in the presence of a carbon-containing inductive substrate, wherein the supply of carbon-containing inductive substrate during the production stage is regulated by an oscillation of the dissolved oxygen partial pressure in the medium.
