From: Multi-scale structural and chemical analysis of sugarcane bagasse in the process of sequential acid–base pretreatment and ethanol production by Scheffersomyces shehatae and Saccharomyces cerevisiae

Figure 3

X-ray diffraction (XRD) pattern of native, cellulignin, sodium hydroxide pretreated, and enzyme hydrolyzed sugarcane bagasse (SB). The crystallinity index (CrI) was found to be increased in cellulignin and NaOH pretreated bagasse. Enzymatic hydrolyzed SB showed the CrI value of cellulignin and NaOH treated bagasse. (a) Natural bagasse, (b) dilute sulfuric acid pretreated bagasse (cellulignin), (c) dilute sodium hydroxide pretreated cellulignin, and (d) enzyme hydrolyzed bagasse. CrI, crystallinity index; SB, sugarcane bagasse; XRD, X-ray diffraction.
