Proposed promoting mechanism of PSS on enzymatic saccharification of GL-P: a non-productive binding of cellulases on residue lignin in normal enzymatic saccharification system; b PSS’s promoting enzymatic saccharification of GL-P by reduced non-productive binding of cellulases on residue lignin (c) by the comparison with the addition of LS to highlight the importance of polymer’s morphology on the interactions between cellulase molecules and promoting additives
