机译:菌丝状菌丛产生酶的过程

摘要

The present invention relates to a process for the production of enzymes by a strain belonging to a filamentous fungus, said process comprising two stages: (a) a first stage of growth of the fungi, in the presence of at least one carbonaceous growth substrate, in a stirred and aerated bioreactor in the batch phase, at a pH less than or equal to 4.6; (b) a second stage of production of enzymes, from the culture medium obtained in the first stage (a), in the presence of '' at least one inducing carbon substrate, at a pH less than or equal to 4.6. Figure 3 to be published
