The injected volume was 20 lL. Sugar standards were used for
quantificationofdifferentsugars(glucose,xylose,mannose,galactose, arabinose and rhamnose) in the samples. Ethanol production was analyzed by Gas chromatography (model 6890,
Agilent), equipped with flame ionization detector and nominal
capillary column (60 m • 530 lm • 5.00 lm).
