Immobilized yeast reactor
Witryna12 lip 2006 · The results above show that the continuous reactor system (ICR) containing brewer’s yeast immobilized on cheap carriers (spent grains, corncobs) was able to operate steadily for almost 2 months. The finished product from ICR was found by consumers to be quite acceptable from a flavour perspective, although a little distinct … WitrynaSeveral studies have indicated that upon immobilization, yeast cells performing ethanol fermentation exhibit more favourable physiological and metabolic properties, indicative of the fact that future developments in the production of ethanol and alcoholic beverages will be directed towards the use of immobilized cell systems.
