: Biosorption represents a feasible alternative for an eco-friendly and cost-effective technology that could help to minimize the harmful environmental impact generated by liquid residues from the industrial activities. Although biosorption has been extensively studied for many years, the process is still only carried out on the laboratory scale. For this reason, the study of biosorption is a high priority in order to optimize the process. This paper aimed to optimize nickel and cobalt biosorption from aqueous solutions using three native metal–resistant <i>Serratia marcescens</i> strains. Initial pH, metal concentration, biomass, and temperature were optimized by Plackett–Burman method, and, finally, biomass and metal concentration were studied using response surface methodology (RSM) to improve nickel and cobalt biosorption. There are only few works about the use of <i>Serratia marcescens</i> as biosorbent.
