This research identifies bacteria that degrade hydrocarbons in waste lubricant oil-polluted soil, indicating their potential for bioremediation.

The study aims to molecularly identify bacteria capable of degrading hydrocarbons in waste lubricant oil-contaminated soil.
Collected contaminated soil samples from various service stations in West Sumatra.
Conducted in vitro experiments to test the hydrocarbon degradation potential of thirteen bacterial isolates.
Identified twelve bacterial species molecularly and performed in situ experiments with selected species.
Identified twelve species of potential hydrocarbon-degrading bacteria, including Alcaligenes sp and Pseudomonas aeruginosa.
In situ experiments with Bacillus sp and Alcaligenes sp showed significant degradation of total petroleum hydrocarbons compared to the control group.
The majority of identified bacteria are ubiquitous, suggesting their broad applicability for bioremediation.

Ahda et al. (2025) studied this question.
