Specific energy demand for the best-case process in comparison to the direct fermentation to 2,3-BDO (reference process). The reference process is more efficient in terms of specific energy demand (a). The maximal applicable acetaldehyde concentration, which is limited due to enzyme stability, is varied to assess the sensitivity of the process to this performance parameter (b). A break-even point with the reference process is found at 600 mM.
