From: Relationship between sugarcane culm and leaf biomass composition and saccharification efficiency
Ethanol yield (bars) and percent conversion of glucan to ethanol (line) in sugarcane culm (light bars) and leaf (dark bars) tissues after 15 h of SSF. Prior to SSF, alcohol-insoluble residue samples were untreated (a) or subjected to dilute acid (DA) (b), hydrothermal (HT) (c) and ionic liquid (IL) (d) pretreatments and then pre-saccharified for 26 h. Least square adjusted means (untreated, n = 3; pretreated, n = 6) are presented ± standard deviation. Letters indicate differences in glucan conversion among genotype × tissue combinations within pretreatment according to Tukey’s honestly significant difference (p ≤ 0.05)
