Oil pollution is an environmental problem of increasing importance. Hydrocarbon-degrading microorganisms, adapted to grow and thrive in oil-containing environments, have an important role in the biological treatment of this pollution. One of the limiting factors in this process is the bioavailability of many fractions of the oil. The hydrocarbon-degrading microorganisms produce biosurfactants of diverse chemical nature and molecular size. These surface-active materials increase the surface area of hydrophobic water-insoluble substrates and increase their bioavailability, thereby enhancing the growth of bacteria and the rate of bioremediation.
石油污染是一个日益重要的环境问题。适应在含油环境中生长和繁殖的烃降解微生物在这种污染的生物处理中发挥着重要作用。这个过程中的限制因素之一是石油许多组分的生物可利用性。烃降解微生物产生化学性质和分子大小各异的生物表面活性剂。这些表面活性物质增加了疏水性水不溶性底物的表面积并提高其生物可利用性,从而促进细菌生长和生物修复速率。
