Abstract

See full text

The presently disclosed subject matter concerns a process for the co-production of glucosamine polymers (chitin, chitosan or any of its derivatives) and polymers containing glucose, mannose and/or galactose, by the high cell density fermentation of the yeast Pichia pastoris in a bioreactor under aerobic conditions. The process can include the use of glycerol byproduct from the biodiesel industry as carbon source. Pure glycerol, pure methanol, glycerol-rich or methanol rich mixtures may also be used as carbon sources. The P. pastoris fermentation process can be duly optimized for attaining high cell densities and high cell wall chitin content. The disclosed subject matter also concerns polymers containing glucose, mannose and/or galactose.
