| 摘 要： | 以糖化率为指标对比白腐菌I.lacteus C与G.lucidum E、褐腐菌Fomitopsis sp.IMER2与P.cocos F预处理玉米秸秆的效果,结果表明:不同菌株处理效果差异很大,白腐菌预处理效果优于褐腐菌,木质纤维素网状结构中木质素去除比纤维素结晶度降低利于提高糖化率。I.lacteus C预处理优势明显,处理30 d糖化率最高,比对照提高135.7%,达62.0%;G.lucidum E处理后仅20 d样品糖化率提高,达42.1%;Fomitopsis sp.IMER2处理后糖化率稍有提高;P.cocos F处理降低糖化率。进一步研究发现I.lacteus C通过改性玉米秸秆提高糖化率:处理30 d可溶性还原糖含量提高287.5%,转化率提高178.3%。

| Abstract: | In this paper,corn stover saccharification rate was determined to evaluate the effect of biological pretreatment by two kinds of basidiomycetes.Two white rot fungi(I.lacteus C and G.lucidum E) and two brown rot fungi(Fomitopsis sp.IMER2 and P.cocos F) were grown on corn stover for different incubation duration.The results indicated white rot fungi was better than brown rot fungi on enhancing saccharification rate and the effects differed a lot between strains of different varieties and genus,which suggested... |
