The purpose of the study was to pretreat fermented rooibos biomass with partially purified horseradish peroxidase (HRP) for lignin removal and to convert delignified biomass to soluble sugars through saccharification with a formulated holocellulolytic enzyme cocktail (HEC). HRP enzyme was extracted from the horseradish root tissue and was partially purified by membrane filters and characterised biochemically. HRP enzyme was us...
