The surface charge on Desulfovibrio desulfuricans particles grown in iron-rich batch culture was monitored using electrophoretic mobility. Negative mobility was seen to tend towards zero as growth proceeded and this correlates with cell aggregation and the formation of a biofilm on a mild steel surface. Aggregate size can further be correlated with the relative amounts of sulphur and iron found in them. However, interference with this aggregation and surface treatments showed complex processes to be involved. Biofilm initiation was found to extend over a more lengthy period after batch growth had ceased and corrosion continued during this time. Whilst prevention of biofilm formation reduced corrosion, SRB biofilm formation and sulphide incorporation did not inevitably lead to corrosion, but was dependant on other factors such as biofilm consortia and oxygen availability. |
