Effect of Lonicera caerulea var. emphyllocalyx Fruit on Biofilm Formed by Porphyromonas gingivalis

Figure 6

LCEE did not degrade the biofilm already formed by P. gingivalis. P. gingivalis JCM12257 was treated with or without LCEE (500 μg/mL) for 72 h (control). In order to evaluate the effect of LCEE on the biofilm already formed by bacteria, control bacteria were further treated with or without LCEE for other 72 h (after). (a) Image of polypropylene tube. (b) Biofilm formation was quantified by safranin red adsorption at 490 nm. Data represent the mean ± SD (n = 3). compared to each untreated group evaluated by Student’s t-test.
