Patent ID: 8614070

Claim:
A process for production of i) a chitin-glucan-complex that comprises chitin, chitosan, and glucan; and ii) biopolymers containing glucose, mannose, and/or galactose, the process comprising fermenting the yeast strain deposited as Pichia pastoris strain DSMZ 70877 in a mineral medium that comprises a nitrogen source other than yeast extract or peptone, and further comprises as a carbon source a) an alcohol, a sugar, an organic acid, a poliol, a fatty acid and/or an amino acid, in a monomeric, dimeric or oligomeric form; or b) a food or industrial waste or byproduct generated by the biodiesel industry, that comprises one or more of the alcohol, the sugar, the organic acid, the poliol, the fatty acid and/or the amino acid, and controlling the pH during fermentation, wherein the content of the chitin-glucan-complex is at least 11.7% of Pichia pastoris biomass produced.
