Anaerobic fermentation profiles of strains TMB 3057 (P. stipitis XR and XDH on plasmid) (A), TMB 3066 (Piromyces XI on plasmid) (B) and TMB 3400 (industrial strain with chromosomally integrated P. stipitis XR and XDH) (C). Mineral medium with xylose (50 g/l) was used. The initial biomass concentration for all strains was 5 g/l. Symbols: ◆ xylose; * xylitol; ■ glycerol; ▲ethanol; × acetate.
