    Interestingly more gold was removed by atomic reduction than by biosorption. Additionally we examined time pH concentration and other factors affecting gold removal. The rate of gold (III) removal by C. krusei increased for 6 h and then stabilized however the rate of removal increased after 22 h and reached a second equilibrium after 68 h.
