AB  - Nowadays, because of substantial use of petroleum-derived fuels the number and 
      extension of hydrocarbon polluted terrestrial ecosystems is in growth worldwide. 
      In remediation of aforementioned sites bioremediation still tends to be an 
      innovative, environmentally attractive technology. Although huge amount of 
      information is available concerning the hydrocarbon degradation potential of 
      cultivable hydrocarbonoclastic bacteria little is known about the in situ 
      long-term effects of petroleum derived compounds on the structure of soil 
      microbiota. Therefore, in this study our aim was to determine the long-term 
      impact of total petroleum hydrocarbons (TPHs), volatile petroleum hydrocarbons 
      (VPHs), total alkyl benzenes (TABs) as well as of polycyclic aromatic 
      hydrocarbons (PAHs) on the structure of bacterial communities of four different 
      contaminated soil samples. Our results indicated that a very high amount of TPH 
      affected positively the diversity of hydrocarbonoclastic bacteria. This finding 
      was supported by the occurrence of representatives of the alpha-, beta-, 
      gamma-Proteobacteria, Actinobacteria, Flavobacteriia and Bacilli classes. High 
      concentration of VPHs and TABs contributed to the predominance of actinobacterial 
      isolates. In PAH impacted samples the concentration of PAHs negatively correlated 
      with the diversity of bacterial species. Heavily PAH polluted soil samples were 
      mainly inhabited by the representatives of the beta-, gamma-Proteobacteria (overwhelming 
      dominance of Pseudomonas sp.) and Actinobacteria.
