The most effective antibacterial activities were obtained with marjoram and clary sage oil, alone and in combination. High concentration of meat extract protected the bacteria from the growth inhibiting effect of marjoram oil, while soy peptone had no such effect. Sucrose intensified the lag phase lengthening by marjoram oil in a dose-independent manner. Keywords Essential oils, Food ingredients, Growth rate, Lag phase اثر ضد باکتریایی روغن های ضروری (اسانس ...
