FIG. 4.
Oxygen consumption rate of N. winogradskyi responding to a pulse of 14.2 mM nitrite during continuous and disrupted feeding in a retentostat run with 100% biomass retention. The same specific maximum oxygen consumption rate of 44 μmol O2 · mg of biomass-C−1 · h−1 was reached after the substrate pulse in both cases at a biomass concentration of 188 mg of biomass-C · liter−1.
