Abstract:

Methods and systems for producing a biofuel using genetically modified ammonia-oxidizing bacteria (AOB) are disclosed. In some embodiments, the methods include the following: providing an AOB that have been genetically modified to include a particular metabolic pathway to enable them to generate a particular biofuel or chemical; feeding a first source of ammonia to the AOB; feeding carbon dioxide to the AOB; and producing at least the biofuel or chemical, nitrite, and an AOB biomass. In some embodiments, the methods and systems include the following: a bioreactor including AOB that have been genetically modified to include a particular metabolic pathway to enable them to generate a particular biofuel; a first source of ammonia; a source of carbon dioxide; and a electrochemical reactor that is configured to electrochemically reduce nitrite produced in the bioreactor to a second source of ammonia.

Claims:

A method for producing a biofuel using genetically modified ammonia-oxidizing bacteria (AOB), said method comprising: providing an AOB that have been genetically modified to include a particular metabolic pathway to enable them to generate a particular biofuel; feeding a first source of ammonia to said AOB; feeding carbon dioxide to said AOB; and producing at least said biofuel, nitrite, and an AOB biomass.
