title: Distribution and characteristic of nitrite-dependent anaerobic methane oxidation bacteria by comparative analysis of wastewater treatment plants and agriculture fields in northern China.
abstract: Nitrite-dependent anaerobic methane oxidation (n-damo) is a recently discovered biological process which has been arousing global attention because of its potential in minimizing greenhouse gases emissions. In this study, molecular biological techniques and potential n-damo activity batch experiments were conducted to investigate the presence and diversity ofM. oxyferabacteria in paddy field, corn field, and wastewater treatment plant (WWTP) sites in northern China, as well as lab-scale n-damo enrichment culture. N-damo enrichment culture showed the highest abundance ofM. oxyferabacteria, and positive correlation was observed between potential n-damo rate and abundance ofM. oxyferabacteria. Both paddy field and corn field sites were believed to be better inoculum than WWTP for the enrichment ofM. oxyferabacteria due to their higher abundance and the diversity ofM. oxyferabacteria. Comparative analysis revealed that long biomass retention time, low NH[Formula: see text] and high NO[Formula: see text] content were suitable for the growth ofM. oxyferabacteria.
