Profiles of first, third, and fifth reuse cycles of immobilized cells of Saccharomyces cerevisiae in CCCAB during fermentations of glucose. (a) glucose consumption profile for immobilized cells in chitosan-covered calcium alginate beads during first, third, and fifth cycle (10 h each cycle); (b) ethanol concentration profile for immobilized cells in chitosan-covered calcium alginate beads during first, third, and fifth cycle (10 h each cycle).
