This invention discloses a bacterial strain for remediating cadmium, mercury, and lead (CdM) contaminated soil and its application, belonging to the field of environmental remediation. This invention screened a strain of Acinetobacter guillouiae FG09 from soil, capable of remediating CdM and CdM contaminated soil (CCTC NO: M 20251636). Furthermore, this invention prepared a chelating agent using extracellular polymers and glutathione from the FG09 strain, and then combined the chelating agent with the bacterial suspension of the FG09 strain to form a composition. Experimental results showed that the bacterial suspension, chelating agent, and composition all significantly reduced the CdM, mercury, and lead content in the soil; the composition showed the most outstanding removal rate of CdM, mercury, and lead in soil with heavy metal contamination, with removal rates exceeding 90% after 5 days of remediation. This invention provides a new biological material for the remediation of heavy metal contaminated soil and has significant implications for environmental protection.
