摘要： The present invention provides a method for constructing a halophilic nitrogen assimilation microbiome, and belongs to the technical fields of microorganisms as well as environmental governance and restoration. According to the present invention, a strain of Psychrobacter aquimaris A4N01 is screened from marine sediments; the strain can assimilate ammonia nitrogen to synthesize organic nitrogen, and simultaneously convert organic matters and phosphorus. A halophilic nitrogen assimilation microbiome developed by the strain has good nutrient conversion removal capacity and settling performance, has wide tolerance to salinity, and can be used in high-salinity wastewater treatment, saline-alkali soil fertilization, etc., so as to realize recycling of nutrient elements such as nitrogen and phosphorus in high-salinity environments. The method is simple in operation and low in costs and is environmentally friendly, therefore having good practical application value.
