Abstract
The fate of pentachlorophenol (PCP) in soil under natural conditions was investigated. It was revealed that the total amount of PCP significantly decreased when soil was inoculated by Streptomyces rochei 303, a strain‐destructor of chlorophenols. The products of PCP transformation, such as tetra‐ and trichlorophenols, pentachloro‐benzene, chlorinated dioxins, were identified after the first month of the experiment. Their quantity was less in the variant with the introduced strain compared to control.
