| Abstract: | Hyper-produced strain of erythritol was studied;the fermentation medium and conditions were optimized by the biotic statistical methods.The study showed that 30% of glucose,0.5% of yeast paste,1% of urea and 0.05% of MgSO_4 were the better components of the culture medium.The optimum fermentation conditions were:temperature 34℃,initial pH 6.0,rotation speed 180rpm and fermentation period of 6d. Under the above conditions,the yield of erythritol reaches 157.4mg/ml.The results from the present study indicate that RH-UV-L4—F9 is a high yield strain on production of erythritol and present application oppor- tunity in industry. |
