FIG 3.

Fermentation profiles of T. maritima strains. Strains were cultivated in 3-liter fermentors at 80°C under anaerobic conditions. (A) The relationship between growth (filled symbols; ●, wild type; ■, Tma100; ▼, Tma200) and maltose utilization (open symbols; ○, wild type; □, Tma100; ▽, Tma200). (B) Comparison of H₂, CO₂ (cumulative), and organic acids (lactate and acetate) produced in the growth phase normalized to wild-type biomass produced in 5 h. (C) Relationship between H₂ production and maltose utilization in the wild-type, Tma100, and Tma200 strains. The error bar represents the SD from triplicate analyses.
