Since that we are facing with a serious problem of bacterial resistance it is necessary to find a new antibacterial agents in fight with it. Frangula alnus is traditionally used plant but its antibiofilm potential is poorly investigated. The aim of the study was to investigate antibiofilm activity of F. alnus ethyl-acetate extract (FA) toward S. aureus ATCC strains and clin. isolates as well as its influence on respiration in planktonic and biofilm form. The qual. GCxGC-MS and quant. LC-MS/MS anal. revealed that FA extract was rich in phenols and flavonoids and emodin, chatechin, and ester 4-ethoxy benzoic acid were the most dominant components. Results obtained through microdillution assay showed that FA possesses strong antibacterial activity. Furthermore, crystal violet staining of biofilm biomass demonstrated that extract had strong effect on biofilm formation of all tested strains while effect on preformed biofilms was less pronounced. The effect on biofilm was confirmed with SEM where the changes in biofilm structure were noticed. The activity of extract on the consumption of O2 and production of CO2 was monitored using the Micro-Oxymax respirometer. Interestingly, respiration of the most strains was decreased in planktonic form as well as in biofilms. Results obtained in this study are a good basis for further research in order to discover the mechanism of action of the FA extract on connection between biofilm and respiration. In the experiment, the researchers used many compounds, for example, ((Oxybis(ethane-2,1-diyl))bis(oxy))bis(ethane-2,1-diyl) bis(2-methylacrylate) (cas: 109-17-1Computed Properties of C16H26O7).
((Oxybis(ethane-2,1-diyl))bis(oxy))bis(ethane-2,1-diyl) bis(2-methylacrylate) (cas: 109-17-1) belongs to alcohols. Because alcohols are easily synthesized and easily transformed into other compounds, they serve as important intermediates in organic synthesis. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.Computed Properties of C16H26O7
