Abstract
The methods are disclosed for sustaining a population of microorganisms in an aqueous fermentation broth used in a process to convert syngas to alcohol when the supply of syngas is impaired. The methods involve supplying at least one formate moiety at a rate and amount sufficient to maintain the population of microorganisms. The introduction of the formate moiety also results in the production of at least one metabolic compound other than ethanol and/or acetate by the microorganisms. The metabolic compound can comprise at least one energy storage compound which can be used to support the microorganisms during processing, storage and reactivation.
