process for the production of chitin-glucan complex comprising chitin / chitosan and glucan; and polymers containing glucose, mannose, and / or galactose from by-products of the biodiesel industry.

摘要

Co-production process of chitin, its derivatives and polymers containing glucose, mannose and / or galactose, by cultivating the pichia pastoris yeast The present invention relates to a process for the co-production of glucosamine polymers (chitin 1 chitosan or any of 1 and glucose 1 mannose and galactose 1 by cultivating pichia pastoris yeast to high cell densities in aerobic bioreactor 1 preferably using the by-product of the glycerol rich biodiesel industry as the main carbon source. high purity glycerol or mixtures containing glycerol may also be used. The present invention further relates to a yeast culture process e.g. pastoris properly optimized for obtaining high cell density and high mass percentage of cell wall 1 chytin as well as polymers containing glucose 1 mannose and / or galactose.
