Abstract
A method for making a chitosan product from yeast cells is disclosed herein. Yeast cells are cultured to form a biomass of yeast cells. The yeast cells are induced to undergo meiosis causing the yeast cells to form asci containing ascospores wherein each ascospore contains a chitosan protective layer in the ascospore wall. Chitosan is extracted from the ascospores, purified to form purified chitosan, and precipitated and dried to form a chitosan product.
