Table 2 Glucose (a) and glycerol (b) fermentation by Trichococcus species. Table shows substrate consumption and product generation (± standard deviation, triplicate assays), measured after 24 h for glucose fermentation experiments and after 40 h for glycerol fermentation experiments. Electron recovery was calculated based on substrate/product consumption/production and excludes electrons used for cellular growth
