1. Determination of composition and structure of exopolymers isolated from marine SRB impucated in a severe corrosion of mild steel. 2. Investigation of metal binding properties of isolated exopolymers. Metal species will include Fe, Cr & Mo.3. Characterisation of the nature of chemically active groups participating in the polymer/metal interactions4. Assessment of the corrosion promoting capacity of the exopolymer fractions. (1) Exopolymers will be harvested from the cultures of marine SRB species grown with and without mild steel surfaces. Extracellular polymeric substances (EPS) will be characterised for their protein and carbohydrate content, and the presence of nucleic acids will be determined. (2) After 18 months, the polysacchride fraction of the EPS will be analysed, and the complete structure of the bacterial EPS will be determined. The CC MS GS FID will be used to provide detailed information of the diversity of SRB exopolmers. (3) After 24 months, crude and purified fractions of exopolymers will be tested for their metal binding capacity to determine the contribution of either proteinacious or carbohydrate parts in complexing Fe, Cr and Mo ions. (4) The final phase of work involves testing the corrosiveness of exopolymer fractions that exhibit different affinities for Fe ions. Techniques of FTIR and scanning probe microscopy will be used to establish the influence of the exopolymers on the corrosion of different types of steel.
