✦ Synopsis

An immobilization technique has been developed for the conversion of both cellobiose and xylose to ethanol, which may be considered as one stage of a process for the conversion of cellulosic biomass to ethanol. Relatively inexpensive charcoal was used as a support material, with 23 mg dry weight of Clostridium saccharolvticum cells per-g dry weight of support. Tests were run for 170 h at 0.15 l/h dilution rate. From a 3% (w/v) sugar mixture, 0.7% (w/v) ethanol was obtained with over 97% cell.obiose and 62% xylose utilization.
