In order to utilize polyvinyl alcohol (PVA) as a gel matrix for the immobilization of microorganisms, PVA was subjected to iterative freezing-thawing. The effects of the procedure on the mechanical characteristics of the PVA hydrogel and the stability of the immobilized microorganisms were investigated. PVA showed rubber-like elasticity after iterative freezing-thawing. Gel strength increased with the iteration number of freezing-thawing until seven iterations. Although the activities of both the free and immobilized cells dereased during the iteration of freezing-thawing, addition of cryoprotectants such as glycerol and skim milk was effective for preventing the decrease in acticity.
