Abstract:
After cellulose, chitin is the second most abundant organic and renewable polysaccharide in nature. This polymer is degraded by enzymes called chitinases which are a part of the glycoside hydrolase family. Chitinases have many important biophysiological functions and immense potential applications especially in control of phytopathogens, production of chito-oligosaccharides with numerous uses and in treatment and degradation of chitinous biowaste. At present many microbial sources are being explored and tapped for chitinase production which includes potential fungal cultures. With advancement in molecular biology and gene cloning techniques, research on fungal chitinases have made fast progress. The present review focuses on recent advances in fungal chitinases, containing a short introduction to types of chitinases, their fermentative production, purification and characterization and molecular cloning and expression.
