摘要: A yeast strain, Saccharomyces cerevisiae KPY32 isolated from pito, a traditional West-African alcoholic beverage, was immobilized in porous ceramic beads as means of improving its ethanol production. Stationary fermentation cultures at different temperatures were made using semi-synthetic medium and parameters including production, sugar consumption, cell growth pH monitored. Glycerol the activity alcohol dehydrogenase (ADH) various systems It found that immobilization resulted improved conversion rates above 93% theoretical value. The also stabilized around 4.0, glycerol production higher, ADH activities higher than those free-cell systems. Ethanol high temperature 37° C by immobilization. promotive action to be related pH, presence enhancement activity.
