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

溶解氧对异养细菌、氨化细菌、化细菌有较大影响。

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.

生物除利用的是将营性菌、菌之化作用与异营性脱菌之脱作用结合。

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.
