Role of Biosurfactants
Oil is a mixture of a large number of components, all of which are hydrophobic. The high molecular weight fraction, especially the polyaromatic hydrocarbons, has a low water solubility that significantly reduces their availability to bioremediating bacteria. The addition of biosurfactants is critical for increasing the bioavailability of these hydrocarbons, and encouraging results were obtained with the use of high molecular weight biosurfactants.
