SEM of biofilm formation and inhibition in vitro assay. The images of the control groups of PA 27853™ and 9027™ in the BHI medium (sucrose, 10%) present numerous bacterial cells and biofilm formation. The magnification used for the image was ×2,000 using a JEOL JS-5600 scanning electron microscope (JEOL United States, Inc., Peabody, MA, United States) at the Characterisation Laboratory, Materials Engineering Department, Centro Federal de Educação Tecnológica de Minas Gerais (CEFET-MG). It was possible to observe a reduction in the number of PA cells and their aggregation in the CFSM treatments when compared to the respective controls.
