硫酸盐还原菌WH16-1对烟草吸收镉的影响
The Effectiveness of Cd Content of Tobacco in Cd-contaminated Tobacco Ssoil by Sulfate-reducing Bacterium WH16-1
摘要
Abstract
This study investigates the effectiveness of decreasing the bioavailability of Cd in pot experiments and in field experiments of Cd-contaminated tobacco soil by sulfate-reducing bacterium WH16-1.The WH16-1 strain was incubated in Cd2+-added tobacco soil pot and field experiments and compared with the uninoculated Cd2+-added soil.Comparison showed that the exchangeable and carbonate-bound Cd in the paddy soil decreased,the Fe-Mn oxide-bound,organic matter-bound and the residual Cd increased.Comparison also showed that the content of chlorophyll,superoxide dismutase(SOD),catalase(CAT)increased and glutaraldehyde(MDA)decreased,the biomass of tobacco increased,and the content of cadmium in tobacco plants decreased.关键词
