Flotation as a bioseparation process for fungi removal

Summary Collectorless flotation has been investigated at a laboratory scale, as a separation technique applied effectively to biomass fine particles (dead free) of Penicillium and Rhizopus; these were previously used for cadmium (a priority toxic pollutant) biosorption from dilute aqueous solutions. The basic parameters of dispersea-air flotation were studied, i.e. solution pH, flotation time, ethanol addition (used as a convenient frother), Cd and biomass concentration.
