Figure 1 : Monosaccharide profiles of Panicum maximum in
different climate conditions: Control (C), Elevated Temperature (eT),
Elevated CO2 (eC) and combined treatments (eT+eC). Mean
values ± SD (n=3) marked with different letters above bars indicate
statistical differences between treatments (p≤0.05, Tukey’s test).
Figure 2 : Principal Component Analysis of Panicum
maximum cell wall composition in different climate conditions: Control
(C), Elevated Temperature (eT), Elevated CO2 (eC) and
combined treatments (eT+eC).
Figure 3 : Lignin monomers of Panicum maximum in
different climate conditions: Control (C), Elevated Temperature (eT),
Elevated CO2 (eC) and combined treatments (eT+eC). CW:
Cell Wall. Mean values ± SD (n=3) marked with different letters above
bars indicate statistical differences between treatments (p≤0.05,
Tukey’s test).
Figure 4 : Carbohydrates content in leaves of Panicum
maximum . Reducing sugars (A) and starch (B). Treatments: Control (C),
Elevated Temperature (eT), Elevated CO2 (eC) and
combined treatments (eT+eC). Mean values ± SD (n=3) marked with
different letters above bars indicate statistical differences between
treatments (p≤0.05, Tukey’s test).
Figure 5 : Glucose (A) and Xylan (B) conversion of untreatedPanicum maximum after enzymatic saccharification at 72 h and 2%
solid content. Treatments: Control (C), Elevated Temperature (eT),
Elevated CO2 (eC) and combined treatments (eT+eC). Mean
values ± SD (n=3) marked with different letters above bars indicate
statistical differences between treatments (p≤0.05, Tukey’s test).
Figure 6 : Binding isotherm of FTCM-depletion assay probes: GC3a
(A), CC17 (B), OC15 (C) and CC27 (D) to C, eT, eC and eT+eC substrates
at 25°C in a 20 mM Tris–HCl (pH 7.5) buffer containing 20 mM NaCl, 5 mM
CaCl2. Treatments: Elevated Temperature (eT), Elevated
CO2 (eC) and combined treatments (eT+eC).
Figure 7: Correlation between accessibility (total cellulose
accessibility (A) as detected by FTCM probes (GC3a + CC17) and total
hemicelluloses accessibility (B) as detected by FTCM probes (OC15 +
CC27)) and percent glucan/xylan hydrolysis.
