Resumen:
The aim of this work was to assess lindane removal from soil slurry by aStreptomycesconsortiumimmobilized in cloth sachets, at different inoculum, lindane and slurry concentrations. In concentratedslurry (soil/water ratio of 2:3), the higher lindane removal (35.3 mg Kg1) was obtained with the mediuminoculum (107CFU g1) 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 soilparticles. 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 Kg1of lindane were removed. Also, aphytotoxicity assay demonstrated that seeds growing on diluted slurries bioremediated during 7 and 14days, showed an improvement in biological parameters, compared to those growing on nonbioremediated slurries. Thus, bioremediated slurries would not have toxic effects on lettuce seeds
