Direct inoculation of bacteria capable of degrading pentachlorophenol (PCP) into PCP-contaminated soil was investigated as a prophylactic measure to reduce the hazards of runoffs when spills occur or when wooden poles freshly treated with PCP-containing preservatives are located near streams and lakes. In laboratory tests at 30 degrees C, the direct addition of 10 PCP-utilizing Arthrobacter cells per g of dry soil reduced the half-life of the pesticide from 2 weeks to <1 day. Soil inoculation also was shown to be an effective way to increase the PCP disappearance rate in a test conducted in an outdoor shed.
将能够降解五氯酚(PCP)的细菌直接接种到受 PCP 污染的土壤中,被视为一种预防性措施,以降低泄漏发生或当用含 PCP 的防腐剂新处理过的木杆位于溪流和湖泊附近时径流的危害。在 30°C 的实验室测试中,直接添加每克干土 10 个利用五氯酚的节杆菌细胞,将农药的半衰期从 2 周缩短至<1 天。土壤接种也被证明是一种有效方法,可提高户外棚内测试中 PCP 的消失率。
