Figure 9From: Chemical and morphological characterization of sugarcane bagasse submitted to a delignification process for enhanced enzymatic digestibilityScanning electron microscopy fracture images of the sugarcane bagasse sample treated with alkaline solutions. (a) NaOH 1%, showing the damaged surface of the cell wall; (b) NaOH 1%, with collapsed cell walls; (c) NaOH 0.5%, cell wall unstructured by peeling off radial layers. Samples underwent roll milling only.Back to article page
