Bioremediation and phytoremediation of pesticide contaminated soil: microbiological study

Abstract

The paper is focused on screening of the approaches to remediate the soil, complex contaminated by obsolete persistent organic pesticides: DDTs and trifluralin. The aim was to increase the biodegradation rates by activation of indigenous soil microflora with mineral and organic amendments. The experiment was carried out in oxic conditions, and cycled anoxic and oxic conditions, with phytoremediation applied afterwards. The effectiveness of the bioremediation procedures for soil microbiota along with degradation of pesticides was discussed. Microbiological analysis of soil at the final of experiments demonstrated the necessity of phytoremediation for soil microflora recovery.
