Abstract

The disclosure relates to the combination of a primary fermentation that converts gas to acetate with a secondary fermentation that converts acetate to a target product. Preferably, the gas contains carbon dioxide, such that the disclosure enables the fixation of carbon dioxide into useful products. The fermentations may be any combination of aerobic and anaerobic, batch and continuous. The fermenting microorganisms may typically be bacterial or fungal.
