Production of chitin fibers by fermentation

In order to find out a mass production method of chitin,this paper studied the production process for chitin by using the fermentation of fungi.Results showed that Absidia fungi yields the highest volume of chitin,producing up to(200 mg) chitin per(200 mL) culture media.The chitin produced through the fermentation process takes the form of hollow fibers,with the length ranging from 50 to 100 mm,similar to that of textile fiber.After treatment,these fibers can be made into a structure similar to hydroentangled nonwoven by the paper making process.The research demonstrated that the chitin fiber made by fermentation has very good bioactivity,is bio-adsorbable,and facilitates the growth of cell and accelerates wound healing when used as medical dressings.
