Fig. 1.3 Immuno-labeled electron micrographs of pretreated, digested corn stover cell walls. Gold
particles (visible as dark dots especially in d and f ) mark the location of Cel7A enzymes digesting
through cell walls following dilute acid pretreatment of varying severity (120 ◦ C c , d ; 150 ◦ C e , f ).
CL, cell lumen; ML, middle lamella; P, pit; 1 ◦ CW, primary cell wall; 2 ◦ CW, secondary cell wall.
Scale bars = 1 μ m a , c, e ; 500 nm b, d, f
