Figure 2From: Ultra-structural mapping of sugarcane bagasse after oxalic acid fiber expansion (OAFEX) and ethanol production by Candida shehatae and Saccharomyces cerevisiaeScanning electron microscopy surface images of the sugarcane bagasse. (a) Native (b) Oxalic acid pretreated (c) Enzymatic hydrolysed. Compacted surface of cell wall showing waxes and deposits in native SB, disruption of cell wall was more evident after oxalic acid mediated pretreatment and enzymatic hydrolysis.Back to article page
