Butanol production by Clostridium beijerinckii BA101 in an immobilized cell biofilm reactor: increase in sugar utilization.

Acetone butanol ethanol was produced in a continuous immobilized cell (biofilm) plug-flow reactor inoculated with Clostridium beijerinckii BA101. To achieve high reactor productivity, C. beijerinckii BA101 cells were immobilized by adsorption onto clay brick.
