Ammonia‐oxidizing bacteria (AOB) have long been considered key to the removal of
nitrogen in activated sludge bioreactors. Culture‐independent molecular analyses have …

Biological nitrification/denitrification is frequently used to remove nitrogen from tannery
wastewater containing high concentrations of ammonia. However, information is limited …

Nitrification of excess ammonia in soil causes eutrophication of water resources and
