Aerobic denitrifiers are a class of denitrifying bacteria which denitrify with aerobic denitrification enzymes under aerobic condition.Compared with the denitrification of traditional bacteria under anoxic condition,the aerobic denitrification technology with aerobic denitrifiers has its unique advantages.The authors reviewed the methods and mechanisms for screening aerobic denitrifiers,including intermittent aeration,acid-base indicator,respiration inhibition,selected culture,dropping reagent,limiting dilu...
