Production of Chitosan from Actinomucor elegans

The effects of carbon source,nitrogen source and inorganic salts on production of chitosan from Actinomucor elegans were investigated.The proportion of two main components(corn steep liquor and corn flour)was optimized by single-factor design and response surface methodology.The results show that the optimal proportion(g/L):corn steep liquor 68,liquefied corn flour 42,KH2PO4 2,MgSO4 2.Under the above conditions,the yield of chitosan reached 2.223 g/L,which increased about 64.30% compared with non-optimization.
