ABSTRACT
Since bioremediation is an environmentally friendly, cost effective approach to treat hydrocarbon-contaminated soils, in this study our aim was to develop a bacterial soil inoculant applicable in elimination of aliphatic, simpleand polyaromatic hydrocarbons from soils. To reach our goal two bacterial strains, Pseudomonas fluorescens BBN1 and Rhodococcus qingshengii BBG1, were selected to investigate their hydrocarbon-degrading abilities at DNA level and in microcosm experiments followed by GC-FID, as well as their ability to tolerate heavy-metal concentrations. Our results revealed that the proposed bacterial soil inoculant is suitable for elimination of aliphatic, monoaromatic and polycyclic aromatic hydrocarbons from soil samples, reaching degradation rates of 95% (n-dodecane), 66% (toluene), 70% (naphthalene) and 67% (phenanthrene) of initial pollutant concentrations within 42 days.
