TL;DR: The bacterium isolated from sea sludge Paracoccus versutus LYM was characterized with the ability of aerobic denitrification and confirmed in terms of the ability to be heterotrophic nitrification and aerobically converting over 95% NO3(-)-N to gaseous products via nitrite.

TL;DR: While NO2(-)-N and NH4(+)-N were present simultaneously, strain LYM could also remove nitrogen compounds thoroughly with sufficient carbon source, but there was no NO2-N reduced as sole nitrogen source in the medium even if C/N ratio reached as high as 30.5%.

TL;DR: Findings suggested the occurrence of NDFO preferred being beneficial via a mixotrophic physiology in the presence of an organic cosubstrate to being out of consideration for metabolic strategy.

TL;DR: In the BioDeNOx process for the nitrogen oxides (NOx) removal, sulfide is supposed to exist in the bioreactor mainly because of bioreduction of sulfite and sulfate.

TL;DR: A viable process concept, based on NO and SO2 absorption into an alkaline Fe(II)EDTA solution in a scrubber combined with biological reduction of the absorbed SO2 utilizing sulfate reducing bacteria (SRB) and regeneration of the scrubbing liquor in a single bioreactor, was developed.
