ABSTRACT:
The invention relates to a method of removing metals from a fossil fuel comprising the steps of contacting the fossil fuel with a biocatalyst selected from the group consisting of an enzyme which degrades porphyrin molecules under conditions suitable for the removal of the metals from the fossil fuel; and separating the metals from the fossil fuel. Preferred embodiments of the biocatalyst include heme oxygenase and cytochrome C reductase, such as cytochrome C reductase from Bacillus megaterium, Catharanthus roseuse, Escherichia coli, animal cells, plant cells or yeast cells. The cytochrome C reductase can be contacted with the fossil fuel in an aqueous medium as a substantially cell-free preparation or cell preparation. In one embodiment of the invention, the metals are recovered from the resulting metal containing stream.
