Figure 4From: Deletion of Caldicellulosiruptor besciiCelA reveals its crucial role in the deconstruction of lignocellulosic biomass Cellulolytic activity (reducing sugars released by in vitro extracellular protein) of the extracellular fraction of Caldicellulosiruptor bescii grown on cellobiose, on carboxymethylcellulose (CMC) (gray bars) after 1 hour and Avicel (white bars) after 24 hours incubation with the extracellular fraction of wild-type, JWCB018 ( ΔpyrFA ΔcbeI ), and JWCB029 ( ΔpyrFA ΔcbeI ΔcelA ) strains.
