Performance evaluation of biosurfactant production by Enterobacter asburiae BR53 isolated from petroleum-contaminated sites in Northeast India and implications for polycyclic aromatic hydrocarbon degradation

Key Points

• Enhanced degradation of polycyclic aromatic hydrocarbons was observed with Enterobacter asburiae, indicating its potential for bioremediation.
• Biosurfactant production levels were significant, with metrics showing effective emulsification properties early in the evaluation.
• Observational analysis across petroleum-contaminated sites highlighted the efficiency of Enterobacter asburiae in degrading harmful compounds.
• These findings support further exploration of biosurfactants for environmental cleanup applications, yet broader studies are needed.
