Process for Making Chitin Derivatives
First Claim
1. A process for increasing the chitosan and/or glucosamine in HYTb comprising:
- forming a mixture comprising HYTb, a microbial composition and solid chitin, wherein said microbial composition comprises one or more microbes that produce chitin digesting enzymes; and
fermenting said mixture for a time sufficient to enzymatically digest all or part of said chitin to form a fermented mixture wherein the amount of at least one of chitosan and glucosamine in said fermented mixture is greater than in said HYTb.

Abstract
Disclosed is a process comprising (1) forming an aqueous mixture comprising a microbial composition and solid chitin, wherein said microbial composition comprises one or more microbes that produce chitin digesting enzymes; and (2) fermenting the mixture for a time sufficient to enzymatically digest all or part of the chitin to form a fermented mixture comprising chitosan and glucosamine. In some embodiments, the chitin is derived from the biodegradation of chitin containing marine Arthropods. In other embodiments, the chitin and other components contained in fungi, filamentous fungi and yeast can be obtained, for example, by the biodegradation of chitin containing fungi, filamentous fungi, yeast and/or insects, preferably using HQE for the digestion. In some embodiments, the process is carried out with a solution that already contains chitosan and/or glucosamine such as HYTb, the aqueous fraction obtained from the biodegradation of chitin containing organisms.

8. A process comprising:
-
mixing a marine animal or marine animal by-product with a first microbial composition to form a mixture, wherein said first microbial composition contains one or more microbes that produce enzymes that digest said marine animal or by-product into solid, aqueous and lipid fractions, wherein said solid fraction comprises chitin and said aqueous phase comprises amino acids, chitosan and glucosamine; fermenting said mixture; separating said mixture into solid, aqueous and lipid fractions, wherein said solid fraction comprises chitin and said aqueous phase comprises chitosan and glucosamine; forming a second mixture comprising said aqueous fraction, chitin and a second microbial composition, wherein said microbial composition comprises one or more microbes that produce chitin digesting enzymes; fermenting said second mixture to form a fermented second mixture; and optionally, separating said fermented second mixture into a second aqueous and second solid fraction, wherein said second aqueous fraction has a higher content of at least one of chitosan and glucosamine as compared to said first aqueous fraction. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
