Figure 3From: Topochemical distribution of lignin and hydroxycinnamic acids in sugar-cane cell walls and its correlation with the enzymatic hydrolysis of polysaccharidesScanning ultraviolet (UV) micrographs of 1-μm transverse sections of sugar-cane cells. The colored pixels represent different UV absorbance values of the cell-wall layers measured at 278 nm with a geometric spatial resolution of 0.25 Ă— 0.25 μm per pixel.Back to article page
