| 摘要: |
| 在研究D-核糖发酵过程中发现，培养基中玉米浆的含量直接 影响着菌体的形态及D-核糖产量。在不同培养基中加入不同浓度的玉米浆，镜检菌株的生 长情况，并测定发酵培养基中D-核糖的产量。研究表明，转酮酶缺陷是突变株在菌体生长 过程中出现链状的内因，而玉米浆中所含的芳香族氨基酸是转酮酶缺陷型突变株在生长过程 中出现链状的外因。 |

| Effect of Corn Steep Liqor on the Growth Pattern of Transketolase-deficient Bacillus Pumlus |
|
|
| Abstract: |
| The growth pattern of transketolase-deficient mutant Baci llus Pumilus and the production of D-ribose was observed . It was found that bo th the growth pattern and the production of D-ribose were changed with the conce ntration of corn steep liqor in the media.The mechanisms including in the chang es were discussed. |
