Lindane and DDT (1,1,1-trichloro-2,2-bis(4-chlorophenyl)ethane) are pesticides from the group of persistent organic pollutants. These compounds, due to lipophilic properties, accumulate in tissues of organisms, are transmitted through the food chain and ultimately threaten human health. The long-term use of pesticides led to soil and water pollution. Microbial degradation of organochlorine compounds is the most eco-friendly method of polluted soil recultivation. Effective degradation of lindane and DDT soil pollution under the influence of introduced destructive bacteria was shown in the laboratory conditions. The concentration of lindane in the soil decreased by 75% and of DDT-by 56% in 30 days. The red clover seedlings increased pesticides degradation in the soil by 20%. The destruction of pesticides in soil was more intense than in the mineral medium. The DGGE analysis of microorganism associations introduced in contaminated soil was possible to follow the survival of the introduced associations. The use of microorganisms-destructors of organochlorine compounds, and plants as well as the biodegradation potential of the soil is a promising direction in the recultivation of polluted soils.

林丹和滴滴涕（1,1,1-三氯-2,2-双（4-氯苯基）乙烷）是持久性有机污染物中的农药。由于亲脂性，这些化合物会在生物体组织中积累，并通过食物链传播，最终威胁到人类健康。长期使用农药导致土壤和水污染。有机氯化合物的微生物降解是污染土壤复垦最环保的方法。在实验室条件下显示了在引入的破坏性细菌的影响下对林丹和滴滴涕土壤污染的有效降解。土壤中林丹的浓度在 30 天内下降了 75%，滴滴涕浓度下降了 56%。红三叶草幼苗使土壤中的农药降解增加了 20%。农药在土壤中的破坏比在矿物介质中的破坏更大。污染土壤中引入的微生物关联的 DGGE 分析可以跟踪引入的关联的生存情况。使用微生物-有机氯化合物的破坏剂和植物以及土壤的生物降解潜力是污染土壤复垦的一个有希望的方向。
