These data suggest that ‘‘CTec
2 + BG’’ has very similar effectiveness to ‘‘CE + BG’’ and that as for CE, CTec 2 exhibits synergy with BG. In addition, previous research
(Zhao et al., 2012) has demonstrated the necessary addition of BG
to the cellulase enzyme to hydrolyse duckweed polysaccharides to
glucose. Thus ‘‘CTec 2 + BG’’ containing CTec 2: 20 U (0.87 FPU) g1
substrate and BG: 2 U g1 substrate was selected as the optimal
enzyme preparation for SSF.
