枯草芽孢杆菌在土壤污染修复中的应用研究
Application of Bacillus subtilis in Soil Pollution Remediation
摘要
Abstract
Bacillus subtilis is widely distributed in the natural environment.Because of its variety,fast growth,easy reproduction and other char-acteristics,it has shown broad application prospects in soil pollution remediation.In order to clarify the application scope,effect and mechanism of Bacillus subtilis in soil remediation,the application status and mechanism of Bacillus subtilis in soil remediation were discussed in detail by referring to a large number of relevant literatures at home and abroad.The results show that Bacillus subtilis has been applied in remediation of heavy metal and radioactive contaminated soil,and the effect of plant-microorganism combined remediation is remarkable.The repair mechanism of Bacillus subtilis on contaminated soil mainly has two direct and indirect ways.The direct way is mainly through the reaction of amino,carboxyl and phosphoric acid groups with heavy metal ions,thus forming precipitation to achieve enrichment.The indirect action mode is to promote plant growth,increase soil respiration and enzyme activity,and reduce the content of available heavy metals by secretions.关键词
