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

Figure 7

LCEE promoted the degradation of biofilm already formed by P. gingivalis subjected to vibrational stimulation. 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. Then, a polyethylene tube was vibrated using a vortex mixer for 10 seconds. (a) Image of polypropylene tube. (b) Biofilm activity 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. LCEE: Lonicera caerulea var. emphyllocalyx extract.
