Biomass concentrations and specific rates of sugar and oxygen uptake as a function of the growth conditions^a

Steady state	N2/air ratio	Biomass concn (g [cell dry wt] · liter−1)	Yield of biomass on glucose (g [cell dry wt] · g of glucose−1)	Specific uptake rate of glucose (C-mmol · g [cell dry wt]−1 · h−1)	Specific uptake rate of oxygen (mmol of O2 · g [cell dry wt]−1 · h−1)
1	250:0	0.54 ± 0.02	0.18	18.4
2	230:20	0.60 ± 0.02	0.20	16.7	0.52
3	200:50	0.55 ± 0.02	0.18	18.2	1.39
4	125:125	0.69 ± 0.04	0.22	14.4	2.83
5	80:170b	0.68 ± 0.01	0.22	14.7	3.61

^aTotal gas flow was 250 N ml · min⁻¹. In steady state 5, DOT was controlled at 5% (13 μmol of O₂ · liter⁻¹).
