This study isolates oil-degrading bacteria from contaminated soil in automobile workshops, aiming to address environmental pollution petroleum spills. Nineteen bacterial were screened, with three S4 (Lysinibacillus macroides), M8 (Serratia marcescens), and M9 (S. showing significant oil degradation potency. In shake flask assays, degraded 57.8%, 60.2%, 58.1% of at a 5% concentration. Molecular identification through 16S rRNA gene sequencing confirmed these strains. Plate assays also supported the potential, growth zones 38.4 ± 1.3 mm (S4), 39.7 1.9 (M8), 41.2 1.7 (M9). Gas chromatography-mass spectrometry analysis treated indicated presence hydrocarbons, phenolic compounds, esters, suggesting microbial interactions, potentially involving breakdown or transformation complex hydrocarbons into simpler compounds by enzymes. These results highlight potential strains, particularly S4, for bioremediation petroleum-contaminated sites.

This research aimed to characterise hydrocarbonoclastic bacteria isolated from naturally hydrocarbon-contaminated springs and the surrounding soils in Agri Valley (Southern Italy) assess effectiveness of bioaugmentation using a four-strain microbial consortium for removing hydrocarbons artificially diesel-contaminated lake waters mesocosm experiments. Four novel bacterial strains were selected experimentation: Gordonia amicalis S2S5, Rhodococcus erythropolis S2W2, Acinetobacter tibetensis S2S8, puyangensis S1W1. The four isolates can use diesel oil as their sole carbon source, some exhibited relatively high emulsifying capacity ability adhere hydrocarbons. Furthermore, genome analyses revealed presence genes associated with degradation, detoxification, transport various contaminants. Mesocosm experiments demonstrated that enhanced capacities native communities remove hydrocarbons, although drastic changes composition (analysed through Next-Generation Sequencing—NGS) observed. Taken together, these results suggest contaminated environments serve valuable reservoir microorganisms significant biotechnological potential, particularly field bioremediation. However, complete understanding efficiently degrade contaminants requires further fully capabilities limitations across different settings.
