This invention discloses a methylbacterium XC1 strain screened from the rhizosphere soil of contaminated paddy fields. Methylbacterium XC1 can stably survive in cadmium-contaminated soil and effectively fix available cadmium in the soil, thereby reducing the content of available cadmium in the soil and achieving effective remediation of cadmium pollution in the soil.

The application discloses Pseudomonas songnenensis, a microbial inoculum and application thereof, and relates to the technical field of environmental microorganisms and solid waste resource technology. The Pseudomonas songnenensis strain JP01 is preserved in the China General Microbiological Culture Collection Center, and has a preservation number of CGMCC No. 37102. The strain has salt and alkali tolerance characteristics, and can degrade coal gangue and promote the release of effective phosphorus, available potassium and effective silicon nutrients. After inoculation for 4 days, under normal conditions, the effective phosphorus content of the strain JP01 treatment group is 758.65% higher than that of the CK group; under salt and alkali conditions, the effective phosphorus content of the strain JP01 treatment group is 4.70 times that of the bacillus megaterium treatment group. The strain has good long-term colonization ability in a coal gangue-salt and alkali soil mixed substrate, and the viable cell count can still be maintained at a high level of 2.72x10 7 CFU / g after 90 days of culture. The application is suitable for coal gangue resource utilization and salt and alkali soil improvement, and has good phosphorus element activation ability and functional stability in a salt and alkali environment.
