| 摘要: |
| 细菌的生长速度和碳源有非常密切的关系，本实验研究不同碳源对反硝化细菌生长的影响，以找到适合用于菌种扩大培养的最佳碳源。实验采用了葡萄糖、酒石酸钾钠、蔗糖、乙酸和乙醇5种碳源作为唯一碳源，接种反硝化细菌进行对比实验，实验采用活菌数来反映不同碳源对反硝化细菌生长的影响。结果显示，葡萄糖促进反硝化细菌生长的作用明显优于其余4种碳源。对反硝化细菌进行扩大培养，葡萄糖的效果是比较好的。 |

| Abstract: |
| The growth of bacteria is relative to carbon sources intimately.The experiment was designed to find the best carbon source in enlarging denitrifying bacteria by research the effect of the growth of denitrifying bacteria with different carbon sources. The 5 carbon sources including glucose,potassium sodium tartrate,cane sugar,acetic acid and ethanol were used as the only carbon source respectively.Took denitrifying bacteria into liquid culture media in the contrast test. Live bacteria number was used to estimate effect of the growth of denitrifying bacteria with different carbon sources.The result made it clear that glucose could promote the growth of denitrifying bacteria more remarkablely than the other.The result indicated that glucose was better than the other in enlarging denitrifying bacteria. |
