Fig. 6From: Visualizing chemical functionality in plant cell wallsAtomic force micrograph of primary and secondary cell wall after delignification. Left, PW of maize parenchyma. Right, SW of maize vascular fiber cell. Delignification condition: 0.1 N HCl and 10% NaClO2 at 1% (w/v) biomass over night (reprinted from [10] with permission). Under this condition, lignin is nearly completely removed, and hemicelluloses are also partially removed. Scale bar = 50 nm. Color bar = 20 nmBack to article page
