Figure 2 :SEM images of Klebsiella pneumoniae ATCC 13883 biofi lms exposed to sub-MICs of essential oil of Cuminum cyminum seeds. Biofi lms of K. pneumoniae formed by 24-hour incubation, in the presence of essential oil. Preparation and observation under the SEM were carried out as described in the text. The bar represents 20 µm. (Reproduction size at column width) a: Control. A biofi lm formed in the medium without essential oil. b: Formed in the presence of 1/4 * MIC of essential oil (0.2-0.87 µg/ml). c: Formed in the presence of 1/2 * MIC of essential oil (0.4-1.75 g/ml)
