Abstract
Oxygenases and methods of biologically upgrading hydrocarbon streams, such as crude oil, using oxygenases are provided herein. The oxygenases can be used to remove impurities such as metals, heteroatoms, or asphaltenes from a hydrocarbon stream. In some cases, the oxygenases can be chemically or genetically modified and can be used in different locations such as petroleum wells, pipes, reservoirs, tanks and/or reactors.
Claims24
A method comprising:
- i) providing a first hydrocarbon stream comprising aromatic molecules;
- ii) contacting the hydrocarbon stream with an oxygenase having a sequence identity to an oxygenase selected from the group consisting of SEQ ID Nos:
- 1-12;
- and
- iii) producing a second hydrocarbon stream having a reduced content of aromatic molecules from the first hydrocarbon stream.
