【摘要】 为了实现味精废水的资源化处理,通过对7株菌资源化处理味精废水的比较,结果表明粘红酵母利用味精废水发酵生产油脂的效果最佳:对味精废水COD_cr降解率高达74.96%,生物量为3.72 g/L,油脂产量为0.12g/L,油脂组成主要为18C和20C的脂肪酸和甘油三酯。并进一步探索了粘红酵母处理味精废水的最优条件:温度30℃,接种量12%,pH5.5。更多还原

【Abstract】 Seven microorganisms were studied in order to make use of monosodium glutamate waste water. As a result, Rhodotorula glutinis was advantageous to treat the waste water because of the most biomass 3.72 g/L and the highest COD C_r reduction 74.96%, at the same time, 0.12 g/L of lipid was got. The components of lipid was dominated by triglyceride and fatty acid with 18C and 20C. Optimum conditions were further studied and the result was abtained: temperature about 30℃, 12% of inoculation, pH5.5.更多还原
