ABSTRACT
The objective of the performed investigations was the microbiological analysis of a wide range of samples collected from natural environments contaminated with oil products, in order to isolate and characterize some hydrocarbon-oxidizing bacterial strains, exhibiting degradative properties for oil products of extensive use and for some chlorinated herbicides belonging to the chloroacetanilide class. Due to these metabolic characteristics, including the increased capacity for synthesis of surfactants, the analyzed isolates can be considered of interest for the bioremediation technologies of environments polluted with such compounds. At the same time, the studied isolates taxonomic appointing to Pseudomonas and Serratia genera, exhibit antagonistic properties against some phytopathogenic bacteria, acting as potential biocontrol agents.
