Microbiological Activity of Soils Contaminated with Benz(")pyrene
The microbiological activity of soils contaminated with benz(a)pyrene was studied. It was shown that benz(a)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(a)pyrene. The microorganisms utilizing mineral nitrogen were tolerant to the contamination with benz(a)pyrene. The activity of soil microorganisms resulted in the formation of additional polyarenes in the soil. Dominant micromycets - Paecilomyces lilacinus и Fusarium moniliforme - were revealed in the soil contaminated with high rates of benz(a)pyrene (3-4 μg/100 g).
