Text this: Stoichiometry and growth yields of amino acid degradation. Substrate degradation, growth yields and doubling times refer to total cultures or total biomass formation of either axenic <i>T. phaeum</i> or syntrophic, binary cultures of <i>T. phaeum</i> and <i>M. thermautotrophicus</i>. All growth experiments were carried out in triplicates. Cell dry weights were estimated using OD-values as a measure of total biomass formation of either <i>T. phaeum</i> alone or <i>T. phaeum</i> with <i>M. thermautotrophicus</i> with a theoretical correlation factor of 250 mg cell dry weight per 1L of a culture of OD₆₀₀ = 1 as described before [7].
