Fig. 5From: Antioxidant and antimicrobial activities of lignin-derived products from all steam-exploded palm oil mill lignocellulosic biomass wasteAntioxidant activity by RSA and EC50 compared to the polyphenol amount. A Polyphenol amount from LML compared to its RSA percentage; B polyphenol amount from LML compared to the EC50; C polyphenol amount from WSL compared to its RSA percentage; D polyphenol amount from WSL compared to the EC50. The alphabetic symbol was used as a post hoc range of DMRT 5% to describe the significance of different pretreatment of each biomassBack to article page
