摘要：

The most suitable conditions for the hardening of alginate bioparticles by Al3+ obtained were: Al3+, 0.3 M; time of treatment 5 min and yeast concentration in the gel, 3 g dry weight/L. The hardened biocatalyst was used to carry out an ethanolic fermentation process in a semi-pilot packed-bed reactor and no breakage of the bioparticles was observed, although the lower part beads had a flat shape, which caused a 11% decrease in bed height. Ethanol productivities up to 31 g/L . h were obtained.
