以硫酸铵为唯一氮源的选择性培养基，通过富集培养，从天然养鱼池塘中筛选出一株能够降解废水中高浓度氨氮的菌株A4，并能耐受废水中的重金属离子，在造纸废水中48 h的降解速率为44%，通过革兰氏染色、菌落形态和分子生物学鉴定为木糖氧化无色杆菌反硝化亚种。
以硫痠銨為唯一氮源的選擇性培養基，通過富集培養，從天然養魚池塘中篩選齣一株能夠降解廢水中高濃度氨氮的菌株A4，併能耐受廢水中的重金屬離子，在造紙廢水中48 h的降解速率為44%，通過革蘭氏染色、菌落形態和分子生物學鑒定為木糖氧化無色桿菌反硝化亞種。

A high effective microorganism A4 degrading ammonia-nitrogen has been isolated from a fish pond by the selected culture medium with (NH4)2SO4 as exclusive nitrogen source.It can bear the poison of heavy metal ion. In the wastewater,the degrading rate of NH4-N by A4 is over 44%within 48 h.Identified by biochemical methods, gram-stain reaction,PCR and electron microscope,this bacterim is Achromobacter xylosoxidans denitrificans.
