From: Analysis of saccharification in Brachypodium distachyon stems under mild conditions of hydrolysis
Scanning electron microscopy showing the effect of different saccharification condition in Brachypodium stems. Images of untreated (A), pretreated only (B, D, F, and H) and pretreated and digested stems (C, E, G, and I). Images B to E show pretreatment at 90°C (B and C without acid and D and E with 2% H2SO4), and images F to I show pretreatment at 130°C (F and G without acid and H and I with 2% H2SO4).
