In dried sample (Sample 2), wrinkles appeared on the surface of the specimen due to the shrinkage of the cell as the moisture evap-orated. The organelles (seen as black dots) were also shrunk due to moisture loss. Moisture removal benefits the processing of biomass by increasing the porosity level of the material and collapsing the structure and in acid hydrolysis; the moisture removal will avoid the acid being diluted as it permeates through the substrate. This is proven when dried sample (Sample2) has produced higher sugar production in acid hydrolysis against wet samples (Sample 1)
