Figure 8From: Chemical and morphological characterization of sugarcane bagasse submitted to a delignification process for enhanced enzymatic digestibilityScanning electron microscopy surface images of the sugarcane bagasse sample treated with alkaline solutions. (a) NaOH 0.5% with bundles starting to come apart; (b) and (c) NaOH 2%, showing unstructured and unattached bundles; and (d) NaOH 4%, showing individual fibers. Samples underwent roll and knife milling before the treatment.Back to article page
