CHARACTERIZATION OF THREE BACTERIAL STRAINS- BIODEGRADANTS OF AROMATIC SUBSTRATES

Three bacterial strains, isolated from contaminated soil, were adapted to degrade increasing concentrations of xenobioticaromatic substrates. Morphological, physiological and biochemical characteristics define them as belonging to the genera Pseudomonas, Alcaligenes and Citrobacter. The strain with highest biodegradative activity is taxonomically related as the closest to Pseudomonas pseudoalcaligenes.
