Abstract
The corrosion potential of steel products exposed in animal buildings caused by microorganisms was investigated by determining the presence of bacteria on metal surfaces. In an initial study, scrapings (1 g from sample surface) of several corroded metal samples collected from three different animal buildings were cultured for total aerobic, anaerobic, and sulfate-reducing bacterial counts. The data obtained revealed high counts (about 108, 106, and 104 for total aerobic, anaerobic, and sulfate-reducing bacteria, respectively) on the corroded metal surfaces in animal buildings. In addition, the presence of biofilms on different metal samples in swine and dairy buildings were revealed by scanning electron microscopy.
