麦麸成分对曲霉多糖产量的影响研究

研究了麦麸及其成分对菌体生长和多糖累积的影响。结果表明,麦麸蛋白和可溶性纤维对曲霉菌体增殖和多糖累积无积极的作用,而麦麸阿魏酸对菌体增殖虽无明显作用但却可显著提高多糖产量。当以葡萄糖发酵培养基培养菌体36h时添加2%的麦麸阿魏酸,使得曲霉多糖产量提高至7.89g/L,比葡萄糖培养基提高了37.9%。 

Effect of wheat bran components on Aspergillus polysaccharide production

Effects of wheat bran and its components on cell growth and polysaccharide accumulation were researched. The results showed that wheat bran protein and soluble fiber played non-active role in Aspergillus cell proliferation and polysaccharide accumulation,while ferulic acid could increase polysaccharide production although no significant effect on cell proliferation. When the cells were cultured in the fermentation medium for 36h,2% ferulic acid was added,then Aspergillus polysaccharide production was improv...
