- The issues of soil contamination in production territories, solid waste landfills and urban environment are discussed by scientists of many countries. The problem of rehabilitation of such territories is considered relevant, and thus requires the corresponding technologies. Regarding phenol compounds the paper describes the recovery options of phenol degraders and its derivatives; suggests using the consortia of bacterial destructors although without the results of their application in real conditions for remediation of the polluted soil. In this study the native saprophyte strain P. putida SU12 with strong desctuctive potential is selected from the consortium of destructors of chronically polluted soils. The in vitro studies of the adaptation of a strain destructor to remediation conditions of chernozem leached in the impurity mode with phenol compounds is conducted. Biological product samples are obtained for phenol destruction in liquid (microcapsules) and solid (sorbent) phases. The dynamics of phenol content change in soil samples from Terengulsky district of Ulyanovsk region in the presence of samples of biological products proves its considerable destruction. The biological product is perspective for field tests since bacteria-destructors quickly adapt to natural conditions of the polluted soil in the presence of soil microflora without losing their destructive properties. Modeling of sorption-biological technology of rehabilitation of soils polluted by phenol compounds is carried out and the scheme of application of the selected biological product sample in natural field conditions is developed.
