β¦ 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.

A new method of physically immobilizing enzymes in poly(2hydroxyethyl methacrylate) membranes was developed in order to obtain suitable biosensors. It was possible to prepare an enzyme sensor based on an oxygen Clark electrode and on glucose oxidase immobilized by low-temperature gamma radiation-ind
Higher activity of ethanol production due to higher density of yeast cells was observed in yeast cells immobilized with artificial polymer carriers of higher water content based on methoxypolyethyleneglycol methacrylate and 2-hydroxyethylacrylate. These polymer carriers were prepared by radiation-in
## Abstract The immobilization of some medically useful enzymes were studied by means of radiationβinduced polymerization at β78Β°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
