An Experimental Research on Anammox Bacteria's Selection

This paper indicated that anammox-bacteria can be selected from both oxic and anaerobic inoculated sludge under anaerobic condition. And the bacteria also can be selected from oxic sludge under aerobic condition. But the time need for selection of Anammox-bacteria was different for those two additions. For anaerobic selection condition, the sludge from beer-wastewater treatment system was best for selecting Anammox-bacteria with 67 days under conditions of pH 8 and 35℃, the time for Anammox-bacteria under aerobic selection was only 20 days which was one month shorter than anaerobic selection.
