Increased ethanol production by thermophilic microorganisms with deletion of individual hfs hydrogenase subunits
Abstract
Disclosed are methods for engineering bacteria, for example, Thermoanaerobacterium saccharolyticum, that convert biomass to ethanol at high yield by deleting a single gene. Deletion of subunit A or subunit B of the hfs hydrogenase, but not deletion of subunit C or subunit D, results in an increase in ethanol yield.
