A bacterial fermentation was carried out in a reactor containing broth with average density 1200 kg/m³ and viscosity 0.02 N.s/m² . The broth was agitated at 90 rpm and air was introduced through the sparger at a flow rate of 0.4 vvm. The fermenter was equipped with two sets of flat blade turbine impellers and four baffles. The dimensions of vessel, impellers and baffle width were: tank diameter, Dt =4 m; impeller diameter, Di = 2 m; baffle width, Wb = 0.4 m; also, the liquid depth was H = 6.5 m
