Cd-tolerant SY-2 strain of Stenotrophomonas maltophilia: a potential PGPR, isolated from the Nanjing mining area in China.

ABSTRACT: Microbial and plant assisted bioremediation is an emerging way for the remediation of soils polluted with heavy metals. To screen the cadmium tolerant bacteria, soil samples were collected from Nanjing mining area, China. The average cadmium content of the mine soil reached 45.71 mg/kg, which was indicating serious pollution and potential ecological risk. From the mine soil, six cadmium tolerant plant growth-promoting rhizobacteria (PGPR) were isolated. The isolated bacterial strain "SY-2" showed maximum cadmium tolerance and it was selected for further experimentation. This strain was identified as Stenotrophomonas maltophilia by 16S rRNA gene sequencing (GenBank accession number MG597057). SY-2 was found to tolerate maximum cadmium at 1.0 mM concentration. This strain also exhibit
