The invention relates to the technical field of microorganisms, and particularly provides a marine heterotrophic nitrification-aerobic denitrification bacterium with a biological denitrification characteristic and biological denitrification application of the marine heterotrophic nitrification-aerobic denitrification bacterium. The name of the strain is Pseudomonas putida 4-HYK, the strain is preserved in the China General Microbiological Culture Collection Center (CGMCC), and the preservation number of the strain is CGMCC NO.28841. The invention further discloses a preparation method of the strain. The strain is separated, screened and identified from a tidal creek of a sea cucumber culture area at the garden mouth of Dalian City, and efficient biological denitrification can be realized in simulated wastewater. 本发明涉及微生物技术领域，具体为提供一种具有生物脱氮特性的海洋异养硝化-好氧反硝化菌及其生物脱氮应用。该菌株名称为恶臭假单胞菌(Pseudomonas putida)4-HYK，该菌种已保藏于中国微生物菌种保藏管理委员会普通微生物中心，保藏编号为CGMCCNO.28841。该菌株从大连市花园口海参养殖区潮沟中被分离、筛选和鉴定，可在模拟废水中实现高效生物脱氮。
