Methods of measuring and evaluating the presence and distribution of sulfate-reducing bacteria are discussed. The microbiological methods are based on cellcounting (enumeration) techniques, microscopic examination, determination of bacterial activity, and immunological detection. Several experimental approaches to these methods are outlined with emphasis on their suitability and limitations in studies of sulfate-reducing bacteria associated with corrosion problems.
Electrochemical methods employed in laboratory studies of corrosion induced by sulfate-reducing bacteria are reviewed, with emphasis on the advantages and limitations of current techniques, such as determination of open circuit potentials, anodic and cathodic polarization curves, polarization resistance measurements, and determination of critical potentials for pitting. The applicability of microbiological and electrochemical techniques to field studies is briefly discussed.
