E-mail: ngeza kth. Chitin nanofibrils ChNF are interesting high-value constituents for nanomaterials due to the enormous amount of waste from the seafood industry. So far, the reported ChNFs are substantially modified and chemically degraded shortened during extraction from the organisms. A mild treatment was developed to preserve the molar mass, aspect ratio, degree of acetylation and crystallite structure. The powder X-ray diffraction analysis showed the preserved crystallite structure after protein removal.

It is mainly produced by fungi, arthropods and nematodes. In insects, it functions as scaffold material, supporting the cuticles of the epidermis and trachea as well as the peritrophic matrices lining the gut epithelium.
Chitin, in which the repeating unit is the same as that in cellulose except that the hydroxyl group at C-2 is replaced by an acetamido group Fig. Polysaccharides which contain amino sugars or their derivatives are called mucopolysaccharides. Chitinase may also be involved in fungal wall synthesis see Chapter 6. Several chitinases, which are glycoside hydrolase family enzymes, are produced by fungi and can have different substrate-binding site structures and are obviously specialised for different functions Zhou et al. Derivatives of chitin and chitosan have found many commercial uses from medicine to cosmetics and dietary supplements, so fungal chitinases have biotechnological applications, also Seidl, ; Hartl et al. Robson and Anthony P.
