Summary

Enzymatic hydrolysates of orange peel contain relatively high levels of galacturonic acid and arabinose which are not fermentable to ethanol by yeasts. We observed complete utilization of both sugars during fermentation of peel hydrolysates by the ethanologenic construct of E. coli KO11. The bacterium exhibits a novel pattern of galacturonic acid fermentation producing equimolar amounts of acetate and ethanol accompanied by carbon dioxide.
