摘要

摘要用随机提取的泛tropha硫磷菌DNA片段作为探针,从台湾含氮废弃物中分离出能同时进行硝化和反硝化的细菌。鉴定出两株分离株,命名为粪Alcaligenes faecalis亚种。菌株1和菌株2。研究了不同介质pH、氧含量、添加不同电子给体或抑制剂对硝化和反硝化的影响。分离菌不仅能进行硝化,而且在有氧存在的情况下也能进行反硝化。氰化钾对脱氮有抑制作用;联氨和羟胺对硝化有抑制作用。粪碱菌亚种粪杆菌菌株2表现出较好的反硝化作用。

[Isolation of bacteria which could perform nitrification and denitrification simultaneously by gene probe].

The bacteria which could perform nitrification and denitrification simultaneously from nitrogen containing wastes in Taiwan were isolated by using the probes made from random DNA fragments of Thiosphaera pantotropha. Two isolates were identified and named Alcaligenes faecalis subsp. faecalis strain 1 and strain 2 respectively. The effects on nitrification and denitrification by different medium pH, oxygen content, addition of different electron donors or inhibitors were studied. The isolates not only could perform nitrification, but also denitrification even in the presence of oxygen. Potassium cyanide could inhibit denitrification; hydrazine and hydroxyamine could inhibit nitrification. Alcaligenes faecalis subsp. faecalis strain 2 shows better denitrification.
