A review. Biosurfactants are surface-active compds. synthesized by a wide variety of microorganisms. They are mols. that have both hydrophobic and hydrophilic domains and are capable of lowering the surface tension and the interfacial tension of the growth medium. Biosurfactants possess different chem. structures - lipopeptides, glycolipids, neutral lipids, and fatty acids. They are nontoxic biomols. that are also exhibit strong emulsification of hydrophobic compds. and form stable emulsions. Polycyclic arom. hydrocarbons (PAHs) can be toxic, mutagenic, and carcinogenic compds. that pollute the environment. They are released to the environment as a result of spillage of oil and byproducts of coal treatment processes. The low water soly. of PAHs limits their availability to microorganisms, which is a potential problem for bioremediation of PAH-contaminated sites. Microbially produced surfactants enhance the bioavailability of these hydrophobic compds. for bioremediation. Therefore, biosurfactant-enhanced soly. of PAHs has potential applications in bioremediation. on SciFinder (R)
