Summary
Alginate solutions with two different M/G (mannuronic acid/guluronic acid) ratios were added dropwise to SrCl2 and BaCl2 solutions. The low M/G ratios (0.27) Sr− and Ba-alginate gel beads were more chemically and physically stable in electrolyte solutions than conventional Ca− alginate gel beads. These gel beads with immobilized yeast cells had normal ethanol productivities.
