Appendix A. Detailed composition and ethanol potential
of biomasses.
Table A1. Composition and ethanol potential of root and top of Angus (A) and root and top
of Colosse (C),
The blue color indicates that the measured xylose and arabinose on the Rezex ROA column
is misleading and the peaks of theses sugars probably overlie with other sugars types,
