摘要

1. A method of producing a chitin-glucan complex and / or derivatives, comprising fermenting Pichia pastoris in a culture medium containing, as a preferred carbon source, a glycerin-rich by-product produced by the biodiesel industry, wherein the content of the obtained chitin-glucan complex and / or derivatives is at least 15% of the total dry cell mass obtained. ! 2. The method according to claim 1, where the by-product produced by the biodiesel industry contains 100% glycerin as a carbon source. ! 3. The method according to claim 1, where the by-product produced by the biodiesel industry, alternatively contains a methanol-rich by-product and / or a mixture of glycerol and methanol. ! 4. The method according to claim 3, where the by-product produced by the biodiesel industry contains 100% methanol as a carbon source. ! 5. The method according to any one of claims 1 to 4, where the culture medium further comprises alcohol, sugar, organic acid, polyol, fatty acid and / or amino acid in monomeric, dimeric or oligomeric forms and / or food or industrial waste or by-products, containing one or more of the compounds indicated above. ! 6. The method according to claim 1, where the temperature is maintained above 37 ° C and / or the pH is below 5 to enrich the chitin-glucan complex and / or derivatives. ! 7. The method according to claim 1, where they maintain the temperature above 45 ° C and / or pH at the level of 5-6 for enrichment of chitin-glucan complex and / or derivatives with chitosan. ! 8. The method according to claim 1, where the temperature is maintained below 35 ° C and / or a pH above 6 to enrich the chitin-glucan complex and / or derivatives with glucan. ! 9. The method according to claim 1, where the content
