Abstract

Hydrocarbon contamination from industries like petrochemicals threatens the environment and public health. Benzene, toluene, xylene, and polycyclic aromatic hydrocarbons in petroleum products are highly toxic. Conventional cleanup methods are costly and risk secondary pollution. This review highlights biosurfactants, microbially produced compounds that enhance hydrocarbon degradation by lowering surface tension and increasing bioavailability. Biosurfactants are biodegradable and eco-friendly, making them a sustainable alternative to synthetic surfactants. The review intends to cover the biosurfactant sources, types, mechanisms, and their applications in hydrocarbon-contaminated environments. Recent bioremediation advancements, including microbial-enhanced oil recovery, soil and water cleanup, and heavy metal removal, are discussed. Optimizing biosurfactant production is also explored, offering a green and effective solution to combat hydrocarbon contamination and promote environmental restoration.
