DOI: 10.1016/j.cej.2018.08.110
Abstract: Abstract This study investigates the biodegradation of electrochemically pre-treated textile effluent. The duration effect of electrochemical oxidation (EO) on enhancement of biodegradability and the biodegradation efficiency on untreated and electrochemically pre-treated effluents were evaluated. The… read more here.

DOI: 10.1016/j.envres.2020.109962
Abstract: Although nitrogen (N) transformations have been widely studied under oxic or anoxic condition, few studies have been carried out to analyze the transformation accompanied with NO2--N accumulation. Particularly, the control of mixed N species in… read more here.

DOI: 10.1016/j.gca.2020.08.007
Abstract: Abstract The biogeochemical cycling of arsenic (As) and antimony (Sb) is coupled with sulfur (S). Biogenic sulfide from microbial sulfate reduction under anaerobic conditions may enhance the release of coexisting As and Sb through the… read more here.

DOI: 10.1038/s41467-017-00912-x
Abstract: Although regime shifts are known from various ecosystems, the involvement of microbial communities is poorly understood. Here we show that gradual environmental changes induced by, for example, eutrophication or global warming can induce major oxic-anoxic… read more here.

DOI: 10.1089/ees.2016.0453
Abstract: Abstract An anaerobic/oxic/anoxic sequencing batch biofilm reactor (A/O/A SBBR) was tested to treat carbon-limited wastewater without external carbon addition. Simultaneous nitritation–denitritation in the oxic period and poly-hydroxybutyrate (PHB)-driven denitritation in the anoxic period were implemented… read more here.

DOI: 10.1093/femsec/fiy040
Abstract: ABSTRACT Sulfate‐reducing bacteria (SRB) and sulfur‐oxidizing bacteria drive major transformations in the sulfur cycle, and play vital roles in oxic‐‐anoxic transitions in lakes and coastal waters. However, information on the succession of these sulfur bacteria… read more here.
