英文摘要: Abstract(#br)Six bacteria strains from heavy-metal-polluted ramie rhizosphere soil were isolated through Cd 2+ stress, which were numbered as JJ1, JJ2, JJ10, JJ11, JJ15, and JJ18. Sequence alignment and phylogenic analysis showed that strain JJ1 belonged to Pseudomonas , strain JJ2 belonged to Cupriavidus , strains JJ11 and JJ15 belonged to Bacillus , and strains JJ10 and JJ18 belonged to Acinetobacter . The tolerance capability of all the strains was the trend of Pb 2+ > Zn 2+ > Cu 2+ > Cd 2+ , the maximum tolerance concentration to Cd 2+ was 200 mg/L, to Pb 2+ was 1600 mg/L, to Zn 2+ was 600 mg/L, and to Cu 2+ was 265 mg/L. Strains JJ1, JJ11, JJ15, and JJ18 could grow well under pH 9.0, and strains JJ2, JJ11, and JJ18 could grow well under 7% of NaCl. The results showed that as a whole...
