Klebsiella oxytoca and application thereof

The invention relates to the technical field of microorganisms, in particular to Klebsiella oxytoca and application thereof. The strain is preserved in the China General Microbiological Culture Collection Center on January 10, 2022, and the preservation number is CGMCC (China General Microbiological Culture Collection Center) NO.24286. Experiments show that the strain can tolerate metal ions such as chloride ions, can perform denitrification in the presence of 3% of chloride ions, effectively removes nitrate nitrogen in a water body, and has a wide application prospect. 本发明涉及微生物技术领域，特别涉及一株产酸克雷伯氏菌及其应用。该菌株于2022年1月10日保藏在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.24286。实验表明，该菌株能够耐受氯离子等金属离子，并能在3％氯离子存在的条件下进行反硝化作用，有效去除水体中的硝态氮，具有广阔的应用前景。
