Experimental studies of immobilized-yeast, packed-bed reactors with reduced CO2 entrapment

Axelsson, Anders LU (1988) In Applied Biochemistry and Biotechnology 18. p.91-109
Abstract
A horizontal packed-bed reactor with baffles (HPBR) and a continuously stirred tank reactor with intermittent paddle agitation have been shown to considerably reduce the CO2 entrapment when glucose is fermented with immobilized baker’s yeast in calcium alginate beads. Using high cell contents in the gel resulted in internal mass transfer hindrance. The highest productivity was obtained with the HPBR giving 29 g EtOH/Lh at an ethanol yield of 90%. The substrate used was 100 g/L glucose. Fermentation of lactose and deproteinized whey by coimmobilized baker’s yeast and |3-galactosidase resulted in much lower productivity-about 5 g EtOH/L.h because of the slow fermentation of galactose.
