Abstract

Il est décrit la production dhydrolysats de sucre à partir de matière cellulosique. La méthode peut être employée, par exemple, dans la production de sucres fermentables pour la production de bioéthanol à partir dune substance ligno-cellulosique. Il est aussi décrit des enzymes cellulolytiques ainsi que leur production par technologie de recombinaison, ainsi que les applications des enzymes et des préparations enzymatiques.
