The use of biological materials for effective removal and recovery of heavy metals from contaminatedwastewaters has emerged as a potential alternative method to conventional treatment techniques. The aim of this paper was the laboratory study of biosorption of toxic metals from aqueous solution by the application of microorganisms (Bacillus laterosporus or Bacillus licheniformis), isolated from polluted (metal-laden) soil. Microorganisms have a high surface area-to-volume ratio, because of their small size and therefore, they can provide a large contact interface, which would interact with metals from the surrounding environment. Microbial metal accumulation has received much attention during recent years, due to the potential use of microorganisms for treatment of metal-polluted water or wastewater streams. Two toxic metals were selected as typical examples: a cation (cadmium) and an oxyanion (hexavalent chromium, and promising results were obtained, under optimized conditions
