/ Process for the co-production of chitin its derivatives and polymers containing glucose mannose and/or galactose by the fermentation of the yeast pichia pastoris

摘要

The present invention relates to a process for the production of glucosamine polymers (chitin, chitosan or derivatives thereof) by a high cell density fermentation of yeast Pichia pastoris in a bioreactor using glycerol by-product from aerobic conditions, preferably from the biodiesel industry, ) And a method of co-producing a polymer containing glucose, mannose and / or galactose. Pure glycerol, pure methanol, glycerol-rich or methanol-rich mixtures can be used as the carbon source. The present invention also relates to a method for the production of a paclitaxel, which is optimized for obtaining polymers containing glucose, mannose and / or galactose as well as high cell density and high cell wall chitin content. It also relates to the fermentation process of P. pastoris .
