Электроповерхностные и каталитические свойства гибридных систем на основе минерала галлуазита с иммобилизованным ферментом

Abstract

The electrosurface properties of halloysite nanotubes and natural halloysite mineral were studied using EPR spectroscopy of pH-sensitive NR as spin probes. It was shown that the more positively charged the surface of the studied materials, the greater the catalytic activity of the immobilized hemicellulase. The highest hemicellulase activity was demonstrated by the enzyme immobilized on halloysite surface by covalent binding with aminopropylethoxysiane (APTES).
