Microalgae break down heavy metal through the mechanisms of bioaccumulation and biosorption. What mechanisms do microalgae use in breaking down petroleum hydrocarbon?
Several phytoremediation techniques such as phytovolatilization and phytotransformation can be used in breaking down petroleum hydrocarbon due to the high volatility of its compounds. Evapotranspiration can also be used to break down petroleum hydrocarbon and control hydraulic flow in contaminated environment. Rhizosphere bioremediation (rhizofiltration) might also be useful for hydrophobic organics.
