Abstract

This project will study the importance and influence of sulphate-reducing bacterial biofilms on immobilisation of metals. A specially-constructed laboratory biocell will be used for biofilm growth under controlled conditions. Biofilm development will be studied in the absence/presence of metals (Fe, Cu, Cd, Hg) singly and in combination, using sulphate-reducing bacterial consortia and single strains. Metal distribution within the biofilm, the relative importance of physico-chemical and biological mechanisms utilised for metal immobalisation, and fundamental variables governing sulphate-reducing bacterial biofilm development, e.g. pH, redox, temperature, flow rate, metal concentration/speciation, sulphide concentration, nutrients, will be characterised enabling quantification and optimisation of operational conditions. Data will be used for modelling of metal immobilisation processes within sulphate- reducing bacterial biofilms and relationship to biocell performance.
