在实验室对每年一次用五氯苯酚(PCP)处理过和未处理过的田间地块(日本目室北海道农业试验站)的土壤进行了五氯苯酚分解活性的测试。当PCP作为五氯苯酚的水溶液加入到两组土壤样品中时，尽管PCP分解微生物的数量相差1000倍，但PCP分解活性没有显著差异。然而，当PCP作为PCP-硅藻土混合物加入时，PCP的分解活性与小区处理的历史有关。PCP田间地块的土壤活性始终高于未处理地块。在未经处理的土壤中加入五氯苯酚并培养后，降解五氯酚的微生物数量增加，3-4周后达到与五氯苯酚处理区相同的数量。
Soil from field plots (Hokkaido Agricultural Experiment Station, Memuro, Japan) that had been treated once a year with pentachlorophenol (PCP) and from untreated plots was tested for PCP-decomposing activity in the laboratory. When PCP as an aqueous solution of pentachlorophenolate was added to both sets of soil samples, no significant difference was noticeable in the PCP-decomposing activity, despite a 1000-fold difference in the number of PCP-decomposing microorganisms. When PCP was added as a PCP-celite mixture, however, PCP-decomposing activity was related to the history of the plot's treatment. The activity of the soil from PCP field plots was consistently higher than that from non-treated plots. When PCP was added to the untreated soil and incubated, the number of PCP-decomposing microorganisms increased, reaching the same order as that of PCP-treated soil plots after 3–4 weeks.
