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10 d处理组的抑制作用高于5 d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。
在實驗室模擬條件下，研究冰凍對淡水型硝化細菌和海水型硝化細菌製劑中氨氧化細菌和亞硝痠鹽氧化細菌活性的影響。結果錶明，冰凍對淡水型硝化細菌和海水型硝化細菌製劑活性均有較為明顯的抑製作用，且10 d處理組的抑製作用高于5 d處理組，對淡水型硝化細菌製劑活性的抑製作用大于海水型硝化細菌製劑。液體硝化細菌製劑在鼕季運輸和保存過程中要採取保溫措施，以避免由于冰凍導緻的菌劑活性降低。

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 for five days ,the inhibitory effect on activity of nitrifying bacteria preparation was greater than on marine nitrifying bacteria preparation .In order to avoid the decrease of bacteria preparation activity because of frost ,insulation measures should be taken to liquid nitrifying bacteria preparation during the transport and storage in winter .
