Fig. 1From: Redox mediators modify end product distribution in biomass fermentations by mixed ruminal microbes in vitroEffect of the redox dyes methyl viologen (0.5 mM), neutral red (1 mM) and safranin O (1 mM) on fermentation end product distribution by mixed ruminal microbes in vitro. Data are calculated based on the mass of alkyl groups (methyl plus methylene groups) in the indicated products, per mg of added switchgrass substrate.Back to article page
