Özet
Chitin is an important polysaccharide found as supporting material in the cell wall of mushrooms. In this study, chitin and chitosan were obtained from the cell wall of two different mushroom species using chemical method and physicochemically characterized. The dry weight chitin contents of the mushroom species were determined as 11.4% for Lactarius vellereus and 7.9% for Phyllophora ribis. Chitosan yields of the chitins isolated from L. vellereus and P. ribis were 73.1% and 75.3%, respectively. While, the maximum degradation temperatures of L. vellereus and P. ribis chitins were found to be 354°C and 275°C by thermogravimetric analysis (TGA), the maximum degradation temperature of the chitosans obtained from these chitins were recorded as 262°C and 229°C, respectively. The crystalline index values of L. vellereus and P. ribis chitins were calculated as 64% and 49%, respectively according to the X-ray diffraction analysis (XRD) results. The scanning electron microscopy (SEM) indicated that there were no nanofiber or nanopores on the surface of the chitins and chitosans obtained from these two mushroom species. The results of this study revealed that L. vellereus and P. ribis had higher chitin contents than some other insects and mushroom species recorded in the literature and these species may be used as a potential chitin sources.
