The formation of microbial biofilms on metal surfaces with the subsequent increase in heat transfer resistance and the induction of microbially influenced corrosion (MIC) is being increasingly recognized as an extremely important economic and safety problem for industrial water systems. The development of sufficiently rugged and accurate monitoring devices by which biofilm formation and activity of microbial biofilms can be monitored non-destructively, directly in water systems is the goal of this research. This on-line systems would allow the effective utilization of minimal levels of biocides and inhibitors as well as permit in situ testing of materials for MIC resistance. Several non-destructive technologies such as the quartz crystal microbalance (QCM), the attenuated total reflectance-Fourier transforming infrared spectrometer (ATR-FT/IR), and a genetically engineered bacterium containing the lux gene cassette in which its bioluminescence can be used to define its presence on coupons are on-line devices which accurately measure biofilm formation. Corrosion activity can be estimated by electrochemical impedance.
