Antibacterial and antibiofilm activities of Trollius altaicus C. A. Mey. On Streptococcus mutans

Inhibitory Effect of Monoterpenoid Glycosides Extracts from Peony Seed Meal on Streptococcus suis LuxS/AI-2 Quorum Sensing System and Biofilm

“…Studies have found that the MIC value of Trollius altaicus C.A. Mey (TA) extract against l of Streptococcus mutans is 10 mg/mL [ 12 ]. However, surprisingly, further investigation revealed that paeoniflorin significantly reduced BF formation in S. suis at subminimum inhibitory concentration (1/2 MIC).…”

“…Determination of MIC and MBC was carried out according to the two-fold serial dilution method [ 12 ], with minor modifications. Specifically, add 100 µL of THB to each well of a 96-well microtiter plate.…”

Biomineral-binding liposomes with dual antibacterial effects for preventing and treating dental caries

“…The inhibitory effect of Mag on the biofilm formation of S. mutans was determined by crystal violet staining. 42 The bacterial suspension was first mixed with serial 2-fold dilutions of Mag in a 1 : 1 (v/v) ratio such that its final concentration ranged from 0.125 MIC to 4 MIC, and the mixture was inoculated into a 96-well plate for 24 h at 37 °C. CHG served as the positive control and BHI broth as the negative control.…”

Simultaneous process optimization of ultrasound-assisted extraction of polyphenols and ellagic acid from pomegranate (Punica granatum L.) flowers and its biological activities

“…The antibacterial activities of pomegranate flower extracts at different concentrations were assayed by using the agar diffusion method [30] , [31] . Exactly 100 μL of bacterial solution at a concentration of 1 × 10 6 CFU/mL was added to BHI agar plates.…”
