    • The invention relates to a method for 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 cyctochrome 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.
    • 本发明涉及一种从化石燃料中去除金属的方法,包括以下步骤:使化石燃料与生物催化剂接触,所述生物催化剂选自于在适于从化石燃料中除去金属的条件下降解卟啉分子的酶; 并从化石燃料中分离金属。 生物催化剂的优选实施方案包括血红素加氧酶和细胞色素C还原酶,例如来自巨大芽孢杆菌的细胞色素C还原酶,长春花,大肠杆菌,动物细胞,植物细胞或酵母细胞。 细胞色素C还原酶可以在水性介质中与化石燃料接触,作为基本上无细胞的制剂或细胞制剂。 在本发明的一个实施方案中,从所得到的含金属流中回收金属。
