Abstract

Pleurotus ostreatus was cultured in a bioreactor equipped with different impeller geometries under non-limiting nutrient conditions. With a Rushton turbine impeller the specific growth rate decreased 30% and pellet diameter was reduced 15% when the aeration rate was increased from 1 to 1.5 vvm. Agitation rate reduced the pellet diameter from 5.1 mm to 2.8 mm using 200 rpm and 400 rpm of agitation, respectively. Specific growth rates of 0.036, 0.020 and 0.041 h^-1 were obtained with Roshton (disc turbine), Helical Ribbon and InterMIG impellers, respectively. Impeller geometry is important to control the pellet size and consequently growth rate of P. ostreatus.
