Resumo: | Polycyclic aromatic hydrocarbons (PAHs) constitute a group of priority pollutants which are present at high concentrations in the soils of many industrial contaminated sites. Pollution by these compounds may stimulate growth of organisms able to live in these environments causing changes in the structure of the microbial community due to some cooperative process of metabolization of toxic compounds. A long-term PAH-contaminated soil was stored for several years and used to analyze the native microbiota regarding their ability to grow on pyrene, benzo[a]pyrene, as well as in mixtures of LMW- and HMW-PAHs. Molecular profiles of the microbial community was assessed by PCR-DGGE of 16S rRNA gene, and the number of bands observed in DGGE analyses was interpreted as dominant microbial members into the bacterial community. Results of PAH-contaminated soil microorganisms showed different profiles in the degradative dynamics when some nutrients were added. Predominant species may play a significative role while growing and surviving on PAHs, and some other metabolically active species have emerged to interact themselves in a cooperative catabolism of PAHs. |

Polycyclic aromatic hydrocarbons (PAHs) constitute a group of priority pollutants which are present at high concentrations in the soils of many industrial contaminated sites. Pollution by these compounds may stimulate growth of organisms able to live in these environments causing changes in the structure of the microbial community due to some cooperative process of metabolization of toxic compounds. A long-term PAH-contaminated soil was stored for several years and used to analyze the native microbiota regarding their ability to grow on pyrene, benzo[a]pyrene, as well as in mixtures of LMW- and HMW-PAHs. Molecular profiles of the microbial community was assessed by PCR-DGGE of 16S rRNA gene, and the number of bands observed in DGGE analyses was interpreted as dominant microbial members into the bacterial community. Results of PAH-contaminated soil microorganisms showed different profiles in the degradative dynamics when some nutrients were added. Predominant species may play a significative role while growing and surviving on PAHs, and some other metabolically active species have emerged to interact themselves in a cooperative catabolism of PAHs. |
