Microbial organisms for nitrogen removal were investigated in poultry manure ; raw poultry manure in hencoop, raw manure in pit, and manure after drying. Ammonium concentration increased from the raw manure in hencoop to that in pit, and then decreased after drying. Nitrate and nitrite were not detected. By the PCR analysis using primers specific for nitrogen metabolizing microorganisms, it was shown that ammonium oxidizer increased in the pit, and then decreased after drying. Denitrifier existed commonly, and anammox was not detected.

对鸡粪、鸡舍生禽粪便、窖池生粪和烘干后粪便中的脱氮微生物进行了研究。氨态氮浓度从鸡舍生粪到窖内升高，干燥后下降。未检出硝酸盐和亚硝酸盐。利用氮代谢微生物特异引物进行的PCR分析表明，氨氧化剂在窖池中先增加后减少。反硝化菌普遍存在，未检出厌氧氨氧化。
