Summary

Thiothrix spp., sulfide oxidizing filamentous bacteria, were found to be the main bacterial component of aquatic biofilms causing biofouling in selected municipal water storage tanks, private wells, and drip irrigation systems in Florida. The water originated from the upper Floridan aquifer and associated aquifers in Central and North Florida. Samples were examined where visible biofilms had a white, slimy, filamentous appearance indicative of Thiothrix spp. The detection of Thiothrix spp. was confirmed by enzyme-liked immunosorbent assay (ELISA). These observations confirm that these bacteria and associated extracellular material play an important role in formation of biofilms, which in turn may induce physical changes leading to significant biofouling. These studies suggest that Thiothrix spp.-associated biofouling occurs at an interface where reduced sulfide-containing water contacts aerated water and a surface or substrate is available for attachment.
