Optimization of culture medium composed of rice by-products for carotenoid production by fermentation of Neurospora crassa
摘要
Abstract
The culture medium composed of rice by-products（rice chaff and defatted rice bran） for carotenoid production by Neurospora crassa was optimized through statistical experiment design and data analysis. The defatted rice bran, （NH4）2SO4, KH2PO4,MgSO4,MnSO4 and CaCI2 were evaluated as factors affecting carotenoid biosynthesis by Neurospora crassa,and the significant factors were screened by a Plackett-Burman design. Then the culture medium was optimized by response surface methodology. Results indicated that defatted rice bran and （NH4）zSO4 were the significant factors on carotenoid production. The optimal culture medium consisted of 64.58% defatted rice bran,33.85% rice chaff and 1.57% （NH4）~O4 at which the yield of carotenoids was gotten up to 366mg/kg culture using the optimized fermentation parameters.关键词
