WebJul 10, 2024 · Despite its versatility and accessibility, chitin, the second most abundant polysaccharide on Earth, has so far been commercially extracted only from crustaceans and to a minor extent from fungi. Insects are a viable alternative source of chitin, but they have not been exploited in the past due to limited availability. WebA novel antifungal peptide with 36 amino acids was identified by functional screening of a marine metagenomic library. The peptide did not show similarity with any existing antimicrobial peptide sequences in the databank. The108 bp ORF designated as mmgp1 was cloned and expressed in Escherichia coli BL21 (DE3) using pET expression system.
WebDec 12, 2013 · The chitin and CMC solutions were mixed with ratio of 5:5, 4:6, 3:7, and 2:8 by weight, respectively. Subsequently, ECH as cross-linker was added to mixture, stirred at 20 °C for 0.5 h to obtain a homogeneous solution, and then kept at 60 °C for 20 min to obtain chitin/CMC hydrogels. WebA solution of α-chitin, in saturated calcium chloride dihydrate–methanol solvent system, is dropped into excess of distilled water with gentle mixing to desolubilize the α-chitin; the obtained chitin hydrogel is decanted several times with distilled water and filtered. α-Chitin sheets are obtained after the evaporation of water.
