Viable cells of Saccharomyces cerevisiae were entrapped within gelatin beads by means of a novel technique using oxystarch as a harmless insolubilizing agent instead of formaldehyde or glutaraldehyde. The beads, after incubation in a nutrient medium, were examined in a packed-bed reactor for the continuous production of ethanol under different experimental conditions. Compared with Ca-alginate and k-carrageenan, oxystarch-hardened gelatin showed the highest cell loading and mechanical stability.

Abstract
Viable cells of Saccharomyces cerevisiae were entrapped within gelatin beads by means of a novel technique using oxystarch as a harmless insolubilizing agent instead of formaldehyde or glutaraldehyde. The beads, after incubation in a nutrient medium, were examined in a packed-bed reactor for the continuous production of ethanol under different experimental conditions. Compared with Ca-alginate and k-carrageenan, oxystarch-hardened gelatin showed the highest cell loading and mechanical stability.File in questo prodotto:
