Abstract
Improved biosorption of uranium by Kluyveromyces marxianus IMB3 biomas s was achieved by increasing the electric field strength of delivered pulses from 1.25kV/cm to 2.5kV/cm. Although this had little or no effe ct on the maximum biosorption capacity (q(max)), at low concentrations of uranium the amount bound to the biomass increased from 70 to 140mg uranium/g biomass. Significant increases in the maximum biosorption c apacities (119 - 180 mg uranium/g biomass) were observed when the puls e field strength was increased from 2.5kV/cm to 3.25kV/cm.
