| 中文摘要: |
| 为获得理想的L-乳酸产生菌，选择适合根霉属微生物生长的土样，利用溴甲酚绿平板结合摇瓶复筛的方法得到了一株有一定L-乳酸积累能力的米根霉Rhizopus oryzae CS323。摇瓶发酵试验显示，在未优化发酵条件的情况下发酵48h，米根霉CS323L-乳酸积累量达到50.1g/L，是一株有良好改造潜力的L-乳酸产生菌，适合作为进一步诱变育种的出发菌株。 |
| 英文摘要: |
| In order to obtain an ideal strain producing L-lactic acid, Rhizopus oryzae strain CS323 was obtained by bromocresol green agar plate and shaking flask screening from soil samples. Shaking flask test showed that, without optimization of fermentation conditions, L-lactic acid accumulation of the strain CS323 was 50.1g/L after 48h fermentation. It was a potential L-lactic acid producer suitable for further mutation. |
