Correlation matrices between all measured markers for the R2 samples when considering a all secretomes and glucose yields R2 vs R0 and R2 vs R1; b all secretomes except that of T. reesei and glucose yields R2 vs R0 and R2 vs R1. Correlation intensity (as the Pearson’s coefficient) between two markers is reflected by the size of the disk and is positive when blue and negative when red. ARA, arabinose content; CEL, cellobionic acid content of the corresponding S2 fraction; CRI, apparent cellulose crystallinity; GLC, glucose content; GLU, gluconic acid content of corresponding S2 fraction; LIG, lignin content; MOR, % of particles of size is below 40 µm; SOR, % water uptake of sample at 90% water humidity; XYL, xylose content in R2; YLD20: glucose yield R2 vs R0; YLD21, glucose yield R2 vs R1
