- W2381514933 abstract "Qing Yuan is one of the biggest electronic wastes dismantling base in China, the production pattern of individual workshop has been going on for more than 20 years. A large number of electronic wastes and treatment residuals were dumped in croplands, ditches and valleys. It made the surrounding soils polluted for a long time by Cd, Cu and Pb. There had lots of researches about the present situation analysis and health risk evaluation for heavy metals contaminated soil surrounding dismantling area. But there still had less reports on the study of bioremediation technologies for the e-waste pollution by combined heavy metals. Four tolerance bacteria was isolated from contaminated soil of e-waste dismantling area of qingyuan by this means of enrichment, domestication and isolation. The tolerance bacteria were identified by analyzed of colony morphology and scanning electron microscope and 16 S rDNA technology. Four strains of HS-01, JH-02, YB-03 and JY-04 were respectively Sporosarcina aquimarina, Sporosarcina saromensis, Bacillus megaterium and Bacillus methylotrophicus. The growth characteristic experiments indicated that the bacteria of HS-01 and JY-04 had same growth cycle, the regulatory phase was 0-8 h, 8-12 h was the logarithmic phase, 12-24 h was stable phase and 24-32 h was decline phase; Bacterial JH-02 and YB-03 had same growth cycle, regulatory phase was 0-4 h, 4-12 h was logarithmic phase, 12-24 h was stable phase, and 24-32 h was decline phase. The optimum temperature and pH of HS-01, JH-02 and JY-04 was 30 ℃ and 8, while YB-03 was 35 ℃ and 7.5 respectively. With the increase of mass concentration of heavy metal ions, biosorption experiments showed that the adsorption amounts of four tolerance bacteria to heavy metal ions gradually increased, but the growth ratios of adsorption amounts and adsorption ratios were gradually decreased. The maximum adsorption amounts of four tolerance bacteria to Cd2+, Cu2+, Pb2+ were 2.25, 2.05, 2.28, 2.25 mg,8.19, 4.95, 8.53, 11.78 mg and 10.84, 10.59, 7.66, 9.02 mg respectively. And the maximum adsorption ratios were 94.4, 99.2, 100, 93.3%, 86.1, 90.8, 88.6, 87.3% and 88.9, 82.2, 81.2, 86.7% respectively. The bacteria of HS-01, YB-03, JY-04 had better adsorption efficiency to Cd2+, JY-04 was optimal to Cu2+, and HS-01, JH-02 was the best to Pb2+. The above results suggests the potential application of four tolerance bacteria to remediate the polluted solution by combined heavy metals, but the remediation mechanism and efficiency of the e-waste polluted soils by combined heavy metals still need to be further research." @default.
