Abstract: Cr6+ is a hazardous heavy metal element to plant growth， and can endanger human and animal health through food chain enrichment. In the present study， Cr6+ resistant strains were screened from soils added with 0.3， 0.5 g·kg-1 Cr6+， in order to provide technical support for microbial remediation of heavy metal pollution. It was shown that 9 Cr6+ resistant strains were screened， all of which could grow normally in media with 0.5， 1.0 mmol·L-1 Cr6+. Among them， strains named as J3， J5 and J8 were able to grow in media with 2 mmol·L-1 Cr6+. Besides， after 48 h cultivation in media with 2 mmol·L-1 Cr6+， Cr6+ content in media with J3， J5， J8 was reduced by 23%，36%， 7%， respectively. Sequencing analysis showed that J3， J5， J8 were Bacillus amyloliquefaciens， Bacillus licheniformis， Bacillus sonorensis， respectively.

Key words: heavy metal Cr6+, heavy metal resistance, soil remediation
