A simple method of preparing a chitin-immobilized alpha-amylase and glucoamylase from the protease- and glycosidase-less Mutant HF-15 of Aspergillus awamori var. kawachi was developed and used for the production of high-glucose syrup. The glucoamylase was tightly bound onto chitin without

Crohn's disease (CD) is associated with elevated anti-glycans antibody response in 60% of CD patients, and 25% of healthy first-degree relatives (HFDRs), suggesting a genetic influence for this humoral response. In mice, anti-glucan antibody response depends on the NLRP3 inflammasome.

The chitinolytic machinery of Serratia marcescens is one of the best known enzyme systems for the conversion of insoluble polysaccharides. This machinery includes four chitin-active enzymes: ChiC, an endo-acting non-processive chitinase; ChiA and ChiB, two processive chitinases moving along chitin chains
