Summary
The product patterns were analyzed for sucrose, fermented by non-axenic continuous cultures, at different pH-values. At pH 4.0–4.5, ethanol was the dominant metabolite. Butyric acid dominated between pH 4.5 and 5.0 while a mixed volatile acid pattern occured at higher pH-values. Hydrogen gas production appeared to be associated with butyric acid and never represented more then 6.5 % of the reducing equivalents of the feed.
