An important indicator of antimicrobial activity is the development of microorganisms andthe difference in their numbers towards samples of whey without the addition of essential oils andextracts. Under the title of each plant, from which extract/EO was obtained, there is stated a numberof analysis providing particular results. The dynamic of micro-flora in whey with the addition ofthyme essential oil or extracts is given in the Figs. 1, 2 and 3.Coli w = coliform bacteria in control sample of whey, Ent w = enterococci in control sample of whey, TMRan w/TMRae w == thermo-resistant aerobic/anaerobic MO in control sample of whey, TPC w = total plate count in control sample of wheyFig. 1: The dynamics of the count of MO in the whey with added thyme essential oil571 | Page
