| Abstract: | Summary Optimum fermentation conditions forZ. ramigera were determined and various parameters which affected adsorption rates of chromium and cadmium ions onZ. ramigera were investigated. At 25°C the optimum adsorption pH of Cr(VI) and Cd(II) ions were 2.0 and 6.0 respectively. The adsorption rate of chromium and cadmium ion increased by increasing initial metal ion concentration up to 75 and 50 ppm respectively: at higher initial metal ion concentrations, the adsorption rates decreased. |
