Enhancement of metal ion adsorption capacity of Saccharomyces cerevisiae's cells by using disruption method

► Disruption of S. cerevisiae's cells by bead mills used as a novel treatment to improve adsorption capacity. ► Optimum condition of adsorption capacity was analyzed by RSM (response surface methodology). ► FTIR and SEM were implied for prepared biosorption analysis and shown good adsorption process on well disrupted cells. ► Results shown disulfides and ester bonds besides carboxyl and hydroxyl functional groups were play important role in metal removal.
