✦ Synopsis


Radiation-induced polymerizations of several acrylic and methacrylic esters at both room temperature and low temperature were carried out. The polymer matrices obtained under the latter conditions were examined as carriers for immobilization of yeast cells. The adhesion of the latter was found to be markedly influenced by both matrix hydrophilicity, determined by equilibrium water content measurements, and porosity, evaluated by optical microscopy and scanning electron microscopy. The ethanol productivity during batch fermentation as a function of these parameters is discussed.

## Abstract The immobilization of some medically useful enzymes were studied by means of radiation‐induced polymerization at βˆ’78Β°C. Glucose oxidase and glucose peroxidase were immobilized in the form of thin membranes inside polyvinyl chloride tubes and on polyethylene films; these membranes showed
