| 摘 要： | 在实验室模拟条件下,研究冰冻对淡水型硝化细菌和海水型硝化细菌制剂中氨氧化细菌和亚硝酸盐氧化细菌活性的影响。结果表明,冰冻对淡水型硝化细菌和海水型硝化细菌制剂活性均有较为明显的抑制作用,且10d处理组的抑制作用高于5d处理组,对淡水型硝化细菌制剂活性的抑制作用大于海水型硝化细菌制剂。液体硝化细菌制剂在冬季运输和保存过程中要采取保温措施,以避免由于冰冻导致的菌剂活性降低。 |

| Abstract: | .. Simulated conditions in the laboratory to study frost effects on activity of ammonia--oxidi-zing bacteria and nitrite--oxidizing bacteria in freshwater and marine nitrifying bacteria preparation.The results showed that frost had obvious inhibitory effect on activity of freshwater and marine nitrif-ying bacteria preparation. And the inhibitory effect on frost for ten days was greater than on frost forfive days, the inhibitory effect on activity of nitrifying bacteria preparation was greater than on marinenitrifying bacteria preparation. In order to avoid the decrease of bacteria preparation activity because offrost, insulation measures should be taken to liquid nitrifying bacteria preparation during the transportand storage in winter. |
| Keywords: | nitrifving bacteria preparation frost activity degradation rate |
