Pseudogulbenkiania ferrooxidans strain 2002 was isolated as a lithoautotrophic, Fe(II)-oxidizing, nitrate-reducing bacterium. Phylogenetically, it is in a clade within the family Neisseriaceae in the order Nessieriales of the class Betaproteobacteria. It is anticipated that comparative genomic analysis of this strain with other nitrate-dependent, Fe(II)-oxidizing bacteria will aid in the elucidation of the genetics and biochemistry underlying this critically important geochemical metabolism.

Riparian zones are recognized as major sources of greenhouse gas emissions, particularly methane (CH). Denitrifying anaerobic methane oxidation (DAMO) has garnered growing attention due to its significant contribution to mitigating CH emissions in wetland environments. Nonetheless, the specific role and microbial mechanisms of DAMO in controlling CH release within riparian zones are still not well comprehended.

Dissolved methane is a hurdle for anaerobic wastewater treatment, which would be stripped into the atmosphere by conventional bubble aeration and increase the release of greenhouse gases into the environment. The high oxygen transfer efficiency and less turbulence in membrane aerated biofilm reactor (MABR) could prevent the stripping of dissolved methane. In this study, an MABR was established to remove dissolved methane aerobically in parallel to the nitrogen removal driven by the anammox process.

Autotrophic antimony (Sb) oxidation coupled to nitrate reduction plays an important role in the transformation and detoxification of Sb. However, the specific oxidase involved in this process has yet to be identified. Herein, we enriched the microbiota capable of nitrate-dependent Sb(III) oxidation and identified a new Sb(III) oxidase in an uncultured member of Symbiobacteriaceae.

In this study, constructed wetland-microbial fuel cell (CW-MFC) filled with modified basalt fiber (MBF) via iron modification was utilized for treating perfluorooctanoic acid (PFOA) containing sewage. Results showed the significant promotion by bioelectricity on ammonium and total nitrogen by 7.80-8.
