WebJul 1, 2006 · Chitin can be processed in the form of films and fibers: fibers were first developed by Austin [83] and then by Hirano [84]. The chitin fibers, obtained by wet-spinning of chitin dissolved in a 14% NaOH solution, can also result of blending with cellulose [85] or silk [86]. WebThe protein acts as an enzyme by breaking down chitin, a polysaccharide found in 5 the walls of many fungi, to its monomers. Because of the resulting more negative water potential in the cytoplasm of the fungus, this effectively leads to "death by osmosis" of anyfungus attacking the grain.
