4.1. Fermentation and reduction
According to Tables 1 and 2, rates of glycolysis were
enhanced in immobilized cells compared to suspended cells.
Both the activities of some major glycolytic enzymes and
the conversion of substrate were higher. In addition, a relatively
higher amount of sugar was converted to ethanol,
glycerol and acetic acid in immobilized cells compared to
suspended cells. Although micro-environmental conditions
are expected to differ substantially between DEAE-cellulose
immobilized cells and calcium-alginate entrapped cells,
