Methods And Systems For Producing Products Using Engineered Iron Oxidizing Bacteria

A system for producing biofuels using genetically modified iron-oxidizing bacteria, said system comprising:

• a bioreactor including IOB that have been genetically modified to include a particular metabolic pathway to enable them to generate a particular biofuel;
• a first source of ferrous iron in fluid communication with said bioreactor;
• a source of water in fluid communication with said bioreactor;
• a source of oxygen in fluid communication with said bioreactor;
• and
• a source of carbon dioxide in fluid communication with said bioreactor.

A method for producing a chemical using genetically modified iron-oxidizing bacteria, said method comprising:

• providing an IOB that have been genetically modified to include a particular metabolic pathway to enable them to generate a particular chemical;
• feeding a first source of ferrous iron to said IOB;
• feeding water, carbon dioxide, and oxygen to said IOB;
• producing at least said chemical, ferric iron, and an IOB biomass;
• electrochemically reducing said ferric iron to a second source of ferrous iron;
• and
• feeding said second source of ferrous iron to said IOB.
