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

溶解氧对异养细、氨化细、化细有较大影响。

The most common method of biological nitrogen removal is by combining the nitrification of the autotrophic nitrobacter and nitrosomonas with the denitrification of heterotrophic denitrifying bacteria.

氮最常利用的是将营性酸、亚酸化作用与异营性脱脱作用结合。

In this paper,the relation of heterotrophic bacteria to nitrogen and phosphorus in marine environment is studied by adding nitrogen and phosphorus to the seawater in mesocosm.

利用海洋围隔态系统实验装置,向海水中施加不同浓度的氮和磷,研究海洋异养细与海水环境中氮、磷的关系。
