Abstract

Abstract: Cultivable Cd2+-resistant bacterial strains were isolated from burdock rhizosphere by pure culture, and Cd2+-resistant MIC and bacterial strain diversity were analyzed. The results showed that 10 Cd2+-resistant strains were isolated and identified as Bacillus subtilis, Enterobacter aerogenes, Enterobacter ludwigi, Klebsiella sp., Pectobacterium carotovorum and Pseudomonas sp. by 16S rDNA sequence. Among these strains, Pectobacterium carotovorum NP22, Enterobacter ludwigii NP23 and Pseudomonas sp. NP39 had the highest MIC, which was up to 400 mg/L Cd2+ on solid LB plate.

Key words: Arctium lappa, rhizosphere, Cd2+-resistant bacteria
