Summary
Immobilization of Saccharomyces cerevisiae as a monocellular layer adhering to a glass support has been achieved by adsorbing Al or Fe(III) ions on the cells or by coating the support with Al(OH)3 or Fe2O3 particles. The initial rate of glucose to ethanol conversion was measured in pure glucose solutions for free cells in suspension, either untreated or submitted to the chemical treatments used for immobilization, and for immobilized cells, using a small reactor (50–70 ml) in closed circuit. The conversion rate of immobilized cells is in the range of 3.5 to 5×10-14 mol/cell·h while that of untreated suspended cells is in the range of 5 to 7×10-14 mol/cell·h.
