| 摘 要： | 研究了嗜鞣管囊酵母(Pachysolen tannophilus)P-01发酵玉米秸秆糖化液生产纤维乙醇的体系。在原料酶解时用磷酸缓冲液(pH4.8、0.0667mol/L KH2PO4-Na2HPO4溶液),更适合P-01发酵;玉米秸秆糖化液的发酵培养基配方为:酵母膏0.3g/L,蛋白胨0.5g/L,尿素0.2g/L,(NH4)2HPO40.1g/L,吐温800.25mmol/L,聚乙烯醇25mg/L,L-谷氨酰胺0.625g/L,pH5.0;添加油酸对发酵结果的影响不明显;在发酵至36h补料,乙醇最终体积分数为2.05%,比对照(1.54%)提高了33.17%。 |

| Abstract: | Optimization of the fermentation conditions on corn stalk saccharified liquid to produce fuel ethanol by Pachysolen tannophilus P-01 was studied.The results showed that choosing the phosphoric acid buffer is more suitable for co-fermentation of fuel ethanol production,and the fermentation medium suitable for saccharified liquid of P-01 was selected as follows:0.3 g/L yeast extract,0.5 g/L peptone,0.2 g/L carbamide,0.1 g/L diammonium phosphate,250μmol/L tween 80,25mg/L PVA,0.625g/L L-glutamine,pH5.0.The impact of oleic acid on fermentation was weak;feeding the batch culture at 36h,the final ethanol concentration reached 2.05%,improved by 33.17%. |
