Antialgal potential of selected botanicals against biofilm isolated from lime plaster

Popis výsledku v původním jazyce

Exterior plasters can be disturbed by biological biofilms. A significant part of the biofilms are green algae. Present chemical preparations for protection of plasters against algae are mostly base on artificial chemicals those can be very often persistent and danger. It is necessary to find new, more natural biocidal substances and mixtures. In the present study, five selected botanicals (thyme oil, cinnamon oil, thymol, carvacrol, eugenol) was tested for their antialgal properties in aquatic test with biofilm isolated from lime plaster. The botanicals were dissolved in an organic solvent dimethysulfoxide (DMSO). The tests were performed in plastic microplates under laboratory conditions in a biological incubator for 14 days. The total inhibition concentration (TIC) was a measured endpoint. The tests with concentrations in range of 200 to 25 mg/L and 0 mg/L were performed. The own solvent was not toxic to biofilm. The results did not show TIC effects for cinnamon oil in the tested range of concentrations. TIC values were observed in the case of thymol and thyme oil (200-100 mg/L) and eugenol or carvacrol (25 mg/L).
