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

溶解氧对异、氨化、硝化有较大影响。

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.

生物除氮最常利的是将营性硝酸、亚硝酸之硝化与异营性脱硝之脱硝合。

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.
