In countries with a long petroleum extraction and processing history, such as Romania, extensive soil areas are often polluted its derivatives, posing significant environmental human health risks. This study explores the diesel biodegradation potential of two native bacterial consortia isolated from hydrocarbon-polluted soils, focusing on their phenotypic molecular characteristics, growth kinetics, alkane hydroxylase activity, hydrolase production, biosurfactant synthesis capabilities. The consortia, CoP1 CoP2, were successfully obtained using standard successive enrichment culture method samples collected region affected by pollution. CoP2 demonstrated efficient diesel-degrading capabilities, achieving 50.81−84.32% degradation when cultured in minimal medium containing 1–10% (v/v) sole carbon energy source. was corroborated activity detection multiple catabolic genes genomes. consortium contains at least four (alkB, alkM, todM, ndoM) well rhamnosyltransferase 1 (rhlAB), while only (ndoM, C23DO). RND transporter gene (HAE1) present both consortia. Secondary metabolites, glycolipid-type biosurfactants, extracellular hydrolases (protease, amylase, cellulase, lipase), produced demonstrate exceptional efficiency making them suited for bioremediation soils contaminated derivatives.
