Bacillus megatherium Z-101, compound microbial cadmium blocking agent containing bacillus megatherium Z-101 and preparation method

The invention relates to the technical field of application of bacillus megatherium, in particular to bacillus megatherium Z-101 as well as a compound microbial cadmium blocking agent and a preparation method. The strain of the bacillus megaterium Z101 is preserved in the Guangdong Microbial Culture Collection Center (GDMCC) on December 11, 2019, and the preservation number of the strain is GDMCCNO: 60928. According to the prepared compound microbial cadmium blocking agent, the activity of heavy metal elements is reduced by 70% or above, the cadmium content of rice is reduced by 50% or above,enrichment of heavy metal elements in other crops is also obviously reduced, and the purpose of safe utilization of medium and light polluted farmlands can be basically achieved. The preparation method is simple and is beneficial to popularization and application. 本发明涉及芽孢杆菌应用技术领域，具体涉及一种巨大芽孢杆菌Z-101及其复合微生物阻镉剂和制备方法。所述巨大芽孢杆菌(Bacillus megaterium)Z101的菌株于2019年12月11日保藏于广东省微生物菌种保藏中心(GDMCC)，菌种保藏号为GDMCC NO：60928。本发明制得的复合的复合微生物阻镉剂实现
