Pseudomonas alcaliphila with partial denitrification function as well as culture method and application of pseudomonas alcaliphila

The invention discloses pseudomonas alcaliphila with a partial denitrification function as well as a screening culture method and an application of the pseudomonas alcaliphila. The pseudomonas alcaliphila has the collection number of CGMCC No.17246, is screened out of municipal sewage treatment plants and can be enriched by an LB culture medium. The pseudomonas alcaliphila can realize rapid stable accumulation from nitrate to nitrite in the denitrification process under the condition that glucose or ethanol serves as a carbon source, and has wide application prospects in the research field of partial denitrification ways. 一种具有部分反硝化功能的嗜碱假单胞菌、其筛选培养方法及应用，所述嗜碱假单胞菌(Pseudomonas alcaliphila)的保藏号为CGMCC No.17246，所述嗜碱假单胞菌是由城镇污水处理厂筛选出来，可使用LB培养基进行富集。所述嗜碱假单胞菌在以葡萄糖或乙醇为碳源的条件下，可实现反硝化过程中硝酸盐到亚硝酸盐的快速稳定累积，在部分反硝化途径的研究领域有广泛的应用前景。
