In addition, Eucalyptusis classified as hard-wood which has a cellular arrangement that is more compactand tighter than softwood (Li et al., 2010a). Consequently, cellulasewas found to hydrolyzeEucalyptusslower than Bagasse.For the pretreated biomasses, over 95% of the cellulose con-verted was in the glucose form. Cellobiose form appeared only inthe early phase of saccharification with [Bmpy][Cl] (Fig. 2). After24 h saccharification, comparable conversion rates (71%) were ob-served on Bagasse pretreated with the different ionic liquids. Asimilar result was obtained fromEucalyptus: conversion rates of60% for [Emim][OAc] and 50% for [Bmpy][Cl]. Compared withuntreated biomasses, both IL pretreatments increased celluloseconversion 3-fold on Bagasse (Fig. 2a), and a higher enhancement(8- and 9-fold; [Bmpy][Cl] and [Emim][OAc], respectively) was at-tained forEucalyptus(Fig. 2b).Interestingly, differences in the conversion rates between the[Emim][OAc] and [Bmpy][Cl] pretreatments were noticeable dur-ing the initial phase of saccharification (0–1 h). On both biomass,an approximate 6- to 9-fold increase in the conversion for 1 hwas attained with the [Bmpy][Cl] pretreatment (Fig. 2a and b).
