Benzо(а)pyrene destruction in soil by the Rhodococcus wratislaviensis KT112-7 strain isolated from waste products of a salt-mining factory

Estimated the ability to degradation of benzo(a)pyrene in soil bacterial strain Rhodococcus wratislaviensis KT112-7 isolated from man-caused mineral formations BKRU1 enterprises of PJSC “Uralkali” (Berezniki, Perm krai). For the experiment, we used sod-podzolic soil, taken from the territory of the biological station (Klyuchi village Dobriansky district, Perm Krai) and technosol from the outskirts Solikamsk (Perm Krai), to which benz (a) pyrene was added at a dose of 100 mg/kg. The introduction of bacteria into the soil led to a decrease in the concentration of benz(a)pyrene. In sod-podzolic soil concentration of benzo(a)pyrene decreased during the month by 26.1% in technosol by 45.4%. The addition of benzoic acid to sod-podzolic soil at a dose of 100 mg/kg enhanced this positive effect of the introduction of bacteria. These data indicate degradation of benzo(a)pyrene in soil strain of R. wratislaviensis KT112-7 in the presence of organic substances which strain is used as the substrate. The data obtained and the strain of R. wratislaviensis KT112-7 can be used in the development of new biotechnologies for environmental remediation from benzo(a)pyrene.
