FIG. 3.
Effect of oxygen supply on the steady-state acetate production rate (qAcet) in two chemostats. Solid circles, Bioflo 3000; open circles, Applicon type. In the initial phase of each run cells were supplied with air (20.95% O2). Agitation rate was fixed at the minimal value at which cells produce no acetate (i.e., 568 and 610 rpm for the two chemostats, respectively). This point is defined as 100% aerobiosis. Next oxygen availability was varied by varying oxygen percentage in the input gas.
