Abstract excerpt
In this study, we successfully generated the mutant strain Bacillus tropicus AT31-1 from AT31 through atmospheric room-temperature plasma mutagenesis. This mutant strain AT31-1 demonstrated an impressive 48.6 % removal efficiency in 400 mg/L lead medium. Comparative genomic analysis showed that the mutant strain AT31-1 had three mutation sites, which affect the efflux RND transporter permease subunit, the...
