| 摘 要： | 对经稀酸预处理的玉米秸秆发酵产糖条件进行研究,通过单因素和正交试验考察绿色木霉培养时间、接种量、培养基液固质量比、装料量对产糖的影响,结果表明：最佳产糖条件为培养时间3d,接种量1.5片,培养基液固质量比为3.5,装料量为8g,在此条件下水解还原糖得率最高为8.01%,从而为玉米秸秆的进一步综合利用提供了参考依据。

| Abstract: | Saccharification conditions of solid-substrate fermentation of corn straws pretreated with diluted acid by Trichoderma virid had been studied.The major affecting factors of the ratio of solid substrate and liquor,cultivation time,inoculums,loading on the influence of product efficiency of reductive sugar.It showed that the optimum conditions for saccharification was the ratio of cultivating 3 days,inculating 1.5 pieces mycelia（diameter 8mm）.Solid liquor and substrate was 3.5 and the loading was 8g per 250mL flask.Under this condition,the highest yield of reducing sugar was 8.01%.All above these resorts provide some references for further use of corn straws. |
