Abstract
Biosurfactants are important agents in the effective uptake of PAHs by bacteria and fungi. Biosurfactants are found as extracellular compounds or localized on the cell surface ofmicroorganisms. For the latter case, the microbial cell itself is a biosurfactant and adheres to hydrocarbon. Those biosurfactants are capable of increasing the bioavailability of poorly soluble polycyclic aromatic hydrocarbons such as phenanthrene and resins . Therefore, the use of biosurfactants should be a promising means to emulsify the polluted oils prior to biodegradation. Many microorganisms, especially bacteria, produce biosurfactants when grownon water-immiscible substrates. Biosurfactants are more effective,selective, environmentally friendly, and stable than many syntheticsurfactants. This study interested with production of biosurfactantsfrom PAH degrading marine bacteria previously isolated from polluted Egyptian soil.
