Bioconversion of PvMYB4-OX transgenic switchgrass biomass to ethanol with or without hot water pretreatment using Saccharomyces cerevisiae D5A. (a, b) Time courses of fermentation of whole plant material without (a) and with (b) hot water pre-treatment in fermentation broths measured by weight loss. (c, d) Final ethanol yields calculated as mg/g cellulose (c) or mg/g biomass (d) from hot water pre-treated and non-treated biomass, with comparison of different control (Ctrl) and PvMYB4-OX lines. (e, f) Correlation between the PvMYB4 transcript level and SSF ethanol yield without pretreatment. Data from lines L1, L6, L7, L8, L9 and L10 (Alamo ST1 background), and 1A, 1B, 1C, 1D, 1E, 2A and 2B) Alamo ST2 genetic background) are used. (g, h) SSF ethanol yield comparison of PvMYB4-OX and PvCOMT-RNAi [9] transgenic lines. All data are means ± SE (n = 3).
