自养微生物

硝化作用主要是由自养微生物和一些异养微生物在好氧条件下产生的；

It is carried out mainly by autotrophic bacteria although some heterotrophic microorganisms may also be involved .

针对自然界中天然半导体矿物和化能自养微生物之间的能量交换途径进行了详细的实验研究。

The energy exchange between natural semiconductor minerals and chemoautotroph microbes was investigated in details in this paper .

同时生物标志化合物资料也表明蓝细菌、厌氧微生物和其他的自养微生物功能群丰度明显增高。

Lipid biomarker records show distinct increase in the abundance of cyanobacteria , anaerobic prokaryotes and other autotrophic microbes .

总体来说，水体中异养微生物数量大，而自养微生物数量小。

Generally , there are large amounts of heterotrophic bacteria and small amounts of autotrophic bacteria in the water body .

研究了筛选的自养和异养微生物菌群的脱氮效果后发现，异养微生物无论是生长还是对NH+4N及NO-2N的去除都明显好于自养微生物。

Removal of inorganic nitrogen containing chemicals by the isolated autotrophic and heterotrophic bacterial populations was investigated . It was shown that both the growth and removal of NH + 4 N and NO - 2 N by heterotrophic bacterial population were much higher than those by autotrophic bacterial population .

自养脱氮工艺是通过自养微生物的代谢实现氮从NH4+-N至N2的转化，整个过程不消耗有机碳源，尤其适合处理高氨氮、低碳氮比的废水。

Autotrophic nitrogen removal process could realize the conversion of ammonium to denitrogen gas by autotrophic bacteria , and it particularly suitable to treat high Ammonium and low C / N ratio wastewaters .
