This study examines the elimination potential of bacterial biomass (Streptomyces rimosus) against lead (II). The biomass was used in a raw state and treated with NaOH. The adsorption was influenced by pH, temperature and contact time. Treated biomass eliminates the largest amount of lead (II) compared to raw biomass. The Langmuir isotherm is the most appropriate to describe our results with maximum capacity of 47.63 mg/g for lead at 45°C. These results suggest that microbial species as bacterial biomass can be used successfully in the treatment of wastewater contaminated by pollutants such as heavy metals.
