Chitosanase, derived from Streptomyces griseus, is primarily used in the enzymatic degradation of chitosan, a polysaccharide derived from chitin. This enzyme is valuable in biotechnology for producing chitooligosaccharides, which have applications in agriculture as plant growth enhancers and in the food industry as functional food additives. In the biomedical field, chitosanase is utilized to create biocompatible materials for wound healing and drug delivery systems. Additionally, it plays a role in environmental applications, such as the treatment of chitosan-containing waste, contributing to sustainable waste management practices. Its ability to break down chitosan efficiently makes it a crucial tool in various industrial and research applications.
