Hydrogen consumption, acetate production and growth of isolate TWA4 under autotrophic, heterotrophic and mixotrophic conditions. Isolate TWA4 grown on modified AC11.1 medium with (a) H2:CO2 only (b) 10 mM glycerol and no overpressure of H2:CO2 and (c) 10 mM glycerol and H2:CO2 provided. Hydrogen is represented by squares, acetate by triangles and optical density by a dashed line. Error bars represent standard error of mean (n = 3).
