Progress in molecular ecology of nitrifying bacteria;

Optimization and application of fluorescence in situ hybridization assay for detecting nitrifying bacteria in environmental samples;

The conversion rate of NH_4~+-N by nitrifying bacteria in filtering troughs of Takingfugu obscurus;

The Immobilization of Nitrobacteria and Its Usage in Waste－ water Treatment(Ⅰ );

Detection of Nitrobacteria Populations in Wastewater of Biological Nitrification Stage by Polymerase Chain Reaction Analysis;

Research on enrichment and isolation techniques for high-efficient nitrobacteria;

Numbers and nitrification rates of heterotrophic bacteria and nitrifiers in self-purification culture of Paralichthys olivaceus;

This inducted the biofilm-formation process is crucial for achieving a multispecies biofilm with heterotrophs and nitrifiers.

Nitrifiers, denitrifiers, nitrification intensity, denitrification potential and denitrifying enzyme activity were determined of the fresh soil samples having been kept placed at 4C (O), moistened to 40% in water holding capacity at room temperature (24C ~ 27C) (M) and flooded (F) at room te.

Nitrobacteria are one of the important group beneficial bacteria in soil.

Sodium alginate gel and polyrinyl alcolid are used as embedding medium to fix nitrobacter and their nitrification activities are measured.

DNB-1 and SRB-2 isolated from flooding water in Daqing oil field were used to study the competitive inhibition relations between the two bacteria species and the effects of nitrate and nitrite amendment.
