Abstract
Systems and methods for processing biological material utilizing chitosan are provided herein. Methods may include the steps of reducing the pH of an amount of culture to about 5 to 7, incorporating an amount of a chitosan solution into the culture to form a mixture, wherein chitosan in the chitosan solution binds to the biological material; increasing the pH of the culture to about 7 to 10, to flocculate biological material in the culture, concentrating the flocculates, reducing the pH of the concentrated flocculates to about 3 to 5, and separating the recovered chitosan solution from the concentrated biological material.
