In the range of the C/N ratio of 1～14, nitrate reduction mainly occurred in the growth phase of the 4～10 hour and there was minim nitrite accumulation in the process.

当C/N在1～14之间变化时，硝酸盐还原基本都发生在菌株生长的第4～10h，整个反硝化过程中亚硝酸盐浓度一直保持在极低的水平。

At the AGU meeting, Francis and former Stanford graduate student Mike Beman will discuss the role of marine archaea in Mexico's Gulf of California, where nitrifying Crenarchaeota appear to be extremely abundant, een at depths of 2,000 feet.

在AGU会议上，Francis和前斯坦福毕业生Mike Beman将详述海洋古细菌在墨西哥加利福尼亚湾的作用，在那里，即使是2000英尺以下，硝化泉古菌的数量也非常巨大。

With sodium succinate as carbon source and bromothymol blue as pH indicator,20 BTB agar plate positive strains were isolated,from which four of them were identified as aerobic denitrifiers.

利用琥珀酸钠作为碳源，溴百里酚蓝作为pH指示剂，共筛选得到20株BTB琼脂平板阳性菌。通过反硝化性能测定，复筛得到4株好氧反硝化细菌。

The mix-culturing fungi-bacteria showed obvious ability to denitrify on slight-anaerobic condition.

将此3种真菌分别和HS-03菌组合，发现组合菌在微厌氧条件下，均有着较强的反硝化能力。

The number of mold, bacteria, culturable microorganisms, aerobic nitrogen-fixing bacteria, anaerobic nitrogen-fixing bacteria, aerobic cellulose decomposition microbes, anaerobic cellulose decomposition microbes were the most in 16-year-old organic tea garden, and the biomass carbon and nitrification of edaphon were also the strongest.

霉菌、细菌、可培养微生物总量、好气性自生固氮菌、嫌气性自生固氮菌、好气性纤维分解菌、嫌气性纤维分解菌均以16年生茶园最多，土壤微生物生物量碳和硝化作用也以16年生茶园最强。

Fermenting Melibiose was negative in 72 h and part ferments-tube of 8 strains appeared positive after 5 d.

生化反应：27株鼠疫菌在还原KNO3、硝化反应、V—P试验、尿素试验、靛基质试验呈阴性。

The amounts of microorganisms in a new denitrification and phosphorus removing integration equipment in its initial stage of running was measured and the change of total bacteria ,Molds,nitrobacteria, Actinomycetes, Nitrobacteria ,Nitrosobacteria and Nitrate reducing bacteria in different times were also studied.

对反硝化聚磷除磷脱氮污水处理新工艺运行初期系统中的微生物数量进行了跟踪检测，并对细菌总数、霉菌、放线菌、硝化细菌、亚硝化细菌、反硝化细菌在不同日期的数量变化进行了研

It can also explain competitions for space and oxygen between ammonia-oxidizers and nitrite-oxidizers and their evolution in nitrifying biofilm.
