Onozuka R-10 is multi-component cellulase enzyme system from Trichoderma viride used to degrade plant cell walls and isolate protoplasts. It is often used in combination with Macerozyme R-10. This preparation has a high cellulase activity, contains hemicellulases, and it degrades mannans, xylans, galactomannans, pectins and other polysaccharides.
