摘要：

The aim of this work was to assess lindane removal from soil slurry by a Streptomyces consortium immobilized in cloth sachets, at different inoculum, lindane and slurry concentrations. In concentrated slurry (soil/water ratio of 2:3), the higher lindane removal (35.3 mg Kg(-1)) was obtained with the medium inoculum (10(7) CPU g(-1)) and the highest lindane concentration tested, at 7 days of incubation. Although, lindane removal was also detected in abiotic controls, probably caused by pesticide adsorption to soil particles. Thus, these parameters were selected for evaluating the pesticide removal in diluted slurry (soil/water ratio of 1:4). After 14 days of incubation, 28.7 mg Kg(-1) of lindane were removed. Also, a phytotoxicity assay demonstrated that seeds growing on diluted slurries bioremediated during 7 and 14 days, showed an improvement in biological parameters, compared to those growing on nonbioremediated slurries. Thus, bioremediated slurries would not have toxic effects on lettuce seeds. (C) 2014 Elsevier Ltd. All rights reserved.
