Microbiological Activity of Soils Contaminated with Benz(")pyrene
The microbiological activity of soils contaminated with benz(<i>a</i>)pyrene was studied. It was shown that benz(<i>a</i>)pyrene affected the abundance of ecological trophic groups of microorganisms and the predominance of micromycete populations. Cellulosolytic microorganisms were the most responsive to the application of benz(<i>a</i>)pyrene. The microorganisms utilizing mineral nitrogen were tolerant to the contamination with benz<i>(a</i>)pyrene. The activity of soil microorganisms resulted in the formation of additional polyarenes in the soil. Dominant micromycets -<i> Paecilomyces lilacinus и Fusarium moniliforme</i> - were revealed in the soil contaminated with high rates of benz(a)pyrene (3-4 μg/100 g).
