The dissolved oxygen had greater effects on heterotrophic bacteria,ammonifying bacteria and nitrifying bacteria.

溶解氧对菌、氨化菌、硝化菌有较大影响。

It also showed that more than one week was needed to activate Nitrosomonas by daily addition of 1.5 g NH4Cl and another 50 ml nitrifying bacteria to this system.

继续添加1.5克氯化和50毫升硝化菌液，需要一星期活化亚硝酸菌。

If the wastewater concentration was too high, it would stimulate fungus, aminate bacteria, denitrifying bacteria and some anaerobic bacteria to propagate.

污水大，会刺激土壤中真菌、氨化菌、反硝化菌及一些厌气性菌的繁殖。
