Elementary composition of biomas, expressed as C-molecular formula, for the different strains and experimental conditions (% O₂ in the inlet air: 21, 11, 8). C:N carbon:nitrogen ratio; H:O hydrogen:oxygen ratio. γ: reduction degree of the biomass. * Data from Lange and Heijnen 2001 [11] for S. cerevisiae.
