Aerobic denitrifying pseudomonas and culture method and application thereof

The invention discloses an aerobic denitrifying pseudomonas which is pseudomonas XD9 (Pseudomonas alcaliphila XD9) and is preserved in the Guangdong Microbial Culture Collection Center (GDMCC) for thepreservation time of December 25, 2018, and the preservation number is GDMCCNo:60534. The pseudomonas has strong heterotrophic nitrification and aerobic denitrification characteristics, and also hasthe capability of tolerating high-concentration organic matters, NH4-N, NO3-N and NO2-N. Therefore, the pseudomonas has obvious application advantages in the aspect of treating NH4-N wastewater with high organic matter content, and has application potential in the aspect of treating actual high-concentration NO3-N and NO2-N wastewater. 本发明公开了一种好氧反硝化假单胞菌，所述菌株为假单胞菌XD9(Pseudomonas alcaliphilaXD9)，保藏于广东省微生物菌种保藏中心，保藏时间为2018年12月25日，保藏编号为GDMCCNo：60534。该假单胞菌具有较强的异养硝化与好氧反硝化特性，同时具有耐受较高浓度有机物、NH-N、NO-N、NO-N能力。表明该假单胞菌在处理含高有机物含量的NH-N废水方面具有明显的应用优势，且在处理实际高浓度NO-N和NO-N污废水方面具有应用潜能。
