This review explores the role of surfactants in enhancing or inhibiting biodegradation hydrophobic organic compounds (HOCs) by microorganisms. Bioavailability, extent to which pollutants can be accessed and metabolized microbes, is a key factor determining degradation efficiency. Hydrophobic compounds, like polycyclic aromatic hydrocarbons, have limited bioavailability due their low aqueous solubility, hindering microbial uptake. Microorganisms utilize strategies such as biofilm formation direct adhesion surfaces overcome this limitation. Surfactants, both synthetic biosurfactants, been explored improve HOC increasing solubility through micelles emulsions. However, also affect altering cell surface properties, leading mixed results Biosurfactants, are more environmentally friendly, show promise without toxic effects surfactants. The highlights complex interactions between surfactants, adhesion, biodegradation, emphasizing need for tailored surfactant formulations optimize bioremediation. Future research should focus on balancing concentration properties enhance contaminated environments.
