Existence of a scaling relation in continuous cultures of Scheffersomyces stipitis : the steady states are completely determined by the ratio of carbon and oxygen uptake rates

Table 1 Yields obtained during carbon- and oxygen-limited growth of continuous cultures of S. stipitis. The biomass yields shown in rows 1–3 were obtained by fitting the data (Additional file 1: Figure S2), and were used to calculate the remaining yields shown in rows 4–5, which appear in the dimensionless Eqs. (36), (37)
