Abstract Under both laboratory-controlled and outdoor conditions, mass culture ofPhormidium bohneri has shown low growth rates and filament aggregate or floc instability. In order to test for a possible carbonaceous supply limitation, a mass transfer characterization study of the reactor used was conducted. To examine different conditions of aeration, the overall volumetric mass transfer coefficient, KLa(C02), and the energy and physical transfer efficiency for CO2 were determined for three air-flow rates and three types of diffuser. For the different aeration conditions studied, the reactor showed adequate mixing properties with respect to CO2. However, under low air-flow rate conditions, even with the most efficient diffuser, the CO2 transfer capacity appeared limiting. On the other hand, at high air-flow rates, floc breakage as a result of shear stress appeared to limit bioreactor efficiency.
