摘要: 针对污染环境生物修复后产生的大量富集植物体低成本快速处理的关键技术问题,选用枯草芽孢杆菌(Bacillus subtilis)、地衣芽孢杆菌(Bacillus licheniformis)等组成的复合菌剂,用印度芥菜(Brassica juncea)等对重金属有很强富集能力的植物作为材料进行超富集植物体减容减重应用基础研究。结果表明,经微生物复合菌剂处理的超富集植物体的体积减容率达到96%,比对照增加23个百分点;纤维素、半纤维素、木质素降解率分别达到69.06%、80.75%、28.59%,分别比对照增加27.35、14.75、5.49个百分点。充分证明微生物复合菌剂对重金属超富集植物体具有显著的减容减重能力和潜在的应用推广前景。

Abstract: : In order to solve the key technical problems of quickly process large quantities of hyperaccumulator plant bodies at low cost after environmental bioremediation,a composite agent consisting of Bacillus subtilis and Bacillus licheniformis, and plants such as Indian mustard (Brassica juncea) with strong enrichment ability for heavy metals were used in fundamental research of reducing the volume and weight of hyperaccumulator plants. The experiments result showed that the volume-reducing rate of hyperaccumulator plants treated with microbial vomposite agents reached 96% with 23 percentage point more than the control group. And the degradation rates of cellulose, hemicellulose and lignin reached 69.06%, 80.75% and 28.59%,with 27.35,14.75,5.49 percentage point more than the control group. The experimental results show that the microbial composite agents have significant volume reduction and weight reduction abilities for heavy metal hyperaccumulators plants and potential application prospects.
