Glc yields at constant glucan loading from forbs and CS. The values are reported as mg/ml in order to facilitate comparison with the experiment shown in Figure 2. Glucan loading was 2 mg/ml, which corresponds to 100% of maximum theoretical yield in other experiments. The pretreatment was AHP, incubation time was 48 hours, and incubation temperature was 50°C. AHP, alkaline hydrogen peroxide; CS, corn stover; Glc, total glucose; GR, goldenrod; LQ, lamb’s quarters; MW, milkweed; QA, Queen Anne’s lace.
