Abstract: One of the biggest challenges of applying heterotrophic nitrification-aerobic denitrification (HN-AD) bacteria to treat high salt organic wastewater lies in the inhibitory effect exerted by salinity. To study the inhibition effect and underlying mechanism induced… read more here.

Abstract: Although heterotrophic nitrification-aerobic denitrification (HN-AD) is promising in nitrogen removal, it remains unclear for most HN-AD strains in physiological characteristics and metabolic mechanisms. In this study, a newly isolated strain Acinetobacter sp.Z1convertednot only inorganic nitrogen,… read more here.

DOI: 10.4186/ej.2019.23.1.1
Abstract: Enterobacter aerogenes was reported as a bacterium capable of heterotrophic nitrification. It is typically found that autotrophic nitrification is greater in rate than the heterotrophic nitrification. However, heterotrophs are faster growing and lesser sensitive than… read more here.
