摘要
Abstract
The single-cell protein(SCP) can be produced by using yeast to ferment glucose and xylose which were from the corn husk hydrolyzate. The crystalline L-arabinose was obtained from the fermentation supernatant. In the orthogonal experiment of sulfuric acid hydrolysis, the optimal conditions were as follows: sulfuric acid mass fraction 1. 5% ,hydrolysis temperature 120℃ , hydrolysis time 3 h,the ratio of solid to liquid (W/V) was 1: 10. Under such conditions, the yield of xylose, arabinose and glucose was 22.17 g/L, 12.29 g/L, 11.16 g/L, respectively. The fermentation performance of xylose and arabinose of four kinds of yeast was examined. The results show that Candida tropicalis had the highest metabolism rates and yield of biomass, in addition, the loss of the L-arabinose is relatively low. The yield of biomass and L-arabinose was 12.6 g/L and 6.8 %, respectively.关键词
