✦ Synopsis

Stmmary: Clostridium acetobutylicum fermented glucose, arabinose, and xylose with a conversion of carbon source into solvents of 32, 29, and 28% respectively. The growth yields (g cells per g sugar) were similar on the three sugars, but glucose or arabinose were consumed in preference to xylose and with faster growth (O.15 or 0.17 h -I as compared with O.i h-l). Solvent yields of about 80% of the maximum were obtained using a i:i glucose:xylose mixture as substrate.
