Abstract

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.

Description

technical field [0001] The invention relates to the technical field of microorganisms, in particular to an aerobic denitrifying pseudomonas and a culture method and application thereof. Background technique [0002] In recent years, with the rapid development of science and technology and the continuous progress of society, human needs are constantly increasing. Large-scale production in industries such as mariculture, industry and agriculture, seafood processing, and petroleum production has led to a large amount of inorganic nitrogen (mainly ammonia nitrogen, nitric acid, etc.) Salt nitrogen, nitrite nitrogen) discharged into the water body, not only causes eutrophication of the water body, pollutes the water ecological environment, seriously affects the water quality, but also causes aquatic animals to lose their balance, anorexia, slow movement, and even death due to excessive nitrogen content . [0003] Traditional biological denitrification includes aerobic nitrificat...
