Satureja parnassica
Table 11 provides the inhibitory effects of the ethyl acetate extract on all bacterial strains. The MIC values ranged from 0.08 mg / ml (P. gingivalis ) to 5.00 mg / ml (E. coli , S. aureus ). However, C. albicans was not affected by the extract fromS. parnassica . Moreover, the extract exhibited bactericidal effects, with 99.9% of obligate anaerobic bacteria, S. aureus ,S. oralis , and S. sobrinus being killed at concentrations ranging from 0.60 mg / ml (P. micra ) to 5.00 mg / ml (S. aureus ).
In the biofilm plate assay, the extract was able to inhibit biofilm formation at a concentration of 1.25 mg / ml. Furthermore, concentrations ranging from 0.60 mg / ml to 0.08 mg / ml resulted in moderate biofilm production, as shown in Figure 2.
