Abstract：The field soil without pesticides application was added with glyphosate isopropylamine and Ba-cillus subtilis Bs -15 to detect the impacts of Bs -15 on the degradation rate of glyphosate isopropylamine and soil microbial communities and functional diversity.The results showed that the degradation rate of glyphosate isopropylamine was about 70% after inoculated with Bs -15 for 96 hours.Those were 66.97% and 71.57%respectively in sterile soil and unsterilized soil.The BIOLOG ECO microplate assay showed that the average well color development (AWCD)value and 5 functional diversity indexes (Shannon index,Shannon uniformi-ty,Simpson index,McIntosh index and McIntosh uniformity)of soil microorganism increased significantly af-ter inoculated with Bs -15.It indicated that Bs -15 could increase the soil microbial activity and functional diversity and revert the microbic system of soil contaminated by glyphosate to some extent.Thus Bs -15 had good application prospect in bioremediation of soil contaminated by glyphosate.
