A. Sakurai et al., Ethanol production by repeated batch culture using yeast cells immobilizedwithin porous cellulose carriers, J BIOSCI BI, 90(5), 2000, pp. 526-529
Ethanol was efficiently produced for 20 d by repeated batch culture using y
east cells immobilized in porous cellulose carriers. The physical structure
of the carrier beads, which had small pores distributed on the enter surfa
ce and relatively large pores distributed in the interior, was found to be
effective for cell immobilization. The effects of chemical modifications to
the basic cellulose carrier on cell immobilization and ethanol production
were also examined in repeated batch cultures. The chemical modifications h
ad little effect on either cell immobilization or ethanol production.
