Since the 1950s, the Air Force has battled microbial contamination of its fuel systems. Within these systems, microbes are commonly found as biofilms adhered to tank coatings. Thus strategies for mitigating microbial contamination of fuel systems include deterring biofilm growth on coatings. This study investigated how Pseudomonas fluorescens biofilms grow on polyurethane coatings, and contribute to the degradation of those coatings. Specifically, we characterized how medium conditions and substrate composition ...
