Abstract

This project relates to the application of high affinity extracellular metal-chelating compounds produced by sulphate-reducing bacteria (SRB) for metal removal and separation from aqueous solution. The main objectives are to identify SRB strains that produce high affinity metal-chelating compounds, to identify and characterise these compounds, and to investigate the production, application and potential of these compounds for metal removal from aqueous solution. SRB strains will be screened for the production of extracellular Cu- and Zn-binding compounds; selected strains will be used for compound preparation and purification, and for determination of metal complex formation constants, factors affecting binding, and fermentation yields of metal binding compounds. Laboratory scale production, purification and demonstration of process feasibility will involve immobilisation of compounds on suitable supports and determination of activity and stability.
