Abstract
Zinc removal from effluent of rubber product manufacturing through biosorption by four microbial species (Zoogloea ramigera Aerobacter aerogenens floc-forming bacteria and floc-forming yeast) was studied. Growth kinetics and exopolymer production by the species cultured on synthetic media were obtained. Studies conducted using rubber effluent with initial zinc concentration of 29 mg per L showed that the initial zinc uptake rates and equilibrium adsorption capacities achieved by the microorganisms ranged from 18.3 to 42.3 mg Zn per g biomass min and 88 to 206 mg Zn per g biomass respectively. A. aerogenes gave the highest initial zinc uptake rate and equilibrium adsorption capacity followed by the floc-forming yeast. Further investigation on the floc-forming yeast showed that the optimum pH for zinc adsorption by the species was 6.5.
