Saccharification of sulfite‐pulped spruce in the (A) absence and (B) presence of ascorbic acid (1 mM), upon substitution of 15% of the proteins in a Celluclast and Novozym 188 (C/N188) blend with the same amount of BSA (blue bar), TaLPMO9A‐Pp (black bar) or TaLPMO9A‐Ao (red bar). For comparison, the results for a reaction with an LPMO‐containing commercial cellulase cocktail, Cellic™ CTec2 (green bar), are included. Note that it has been shown previously that in the absence of an externally added reductant (as in panel A) LPMO activity on this substrate is low.32
