【摘要】 本文研究了以稻草秸秆为原料经机械粉碎等处理后,用康宁木霉、黑曲霉、绿色木霉所产纤维素酶和米根霉对其进行同时糖化发酵生产乳酸。本次试验分别采用培养温度、CaCO3的添加次序、装液量、培养时间四个因素,重复试验逐一确定出最优的单因素条件,确定出在最佳试验条件下(培养温度为30℃、每隔24h添加1.5%CaCO3、装液量为70mL、培养时间为72h)。黑曲霉与米根霉同时发酵时产乳酸量可达到22.6mg/ml。更多还原

【Abstract】 Studied take the straw stalk as raw material after processing and so on machinery smashing.With Trichodermako ningi、Aspergilliusn ige,Trichodermav irid produces the cellulase and the Rhizopus oryzae enzyme simultaneously saccharify the yeast solution produces the actic acid.The experimentation were used to temperature,the order of append CaCO3,the attire liquid volume,time on incubation four training time,experimentation determine the optimal one by one single factor,determine the best experimental conditions(temperature 30℃ and each 24 add 1.5% CaCO3 and volume 70mL,training for 72 hours).Aspergilliusn ige and Rhi.oryzae while producing lactic acid fermentation can be achieved 22.6mg/ml.更多还原
