Composition of extracted fungal cell walls as indicated by infrared spectroscopy

, : Composition of extracted fungal cell walls as indicated by infrared spectroscopy. Arch Biochem Biophys 120(3): 628-637

Materials have been removed from the hyphal walls of Polyporus myllitae Cke. et Mass. by various chemical treatments. Infrared spectroscopy has been used in an attempt to determine the chemical composition of the residues. [alpha]-Chitin was shown to be the principal constituent possibly accompanied by [beta]-l,3-glucan. There was evidence also of the presence of carboxyl groups. Hyphae of a number of species of fungi from diverse taxonomic groups were extracted successively with potassium hydroxide and glacial acetic acid-hydrogen peroxide, and infrared spectra of the residues were determined. The fungi were divided into two groups on the basis of their spectra: Group I included species having cellulose and Group II those having a -chitin as a significant constituent. The residues of Epicoccum species possibly contained both cellulose and chitin.
