Abstract: | Fructose and H2 were compared as electron donors for hydrogenation of carbon-carbon double bonds using Acetobacterium woodii. Caffeate was used as a model substrate. An electron donor was required and both fructose and H2 were suitable. With fructose as the donor, the K
s for caffeate was 0.5 mM and the V
max was 678 mmol kgdry weight
−1 h−1.␣Fructose oxidation was coupled very efficiently to caffeate reduction by an alteration in the fructose fermentation so that
acetate was no longer produced.
