Figure 2.
Zones of growth inhibition after the treatment of bacteria with volatile and liquid fractions of EOs assessed with the inverted Petri dish method and disc diffusion technique, respectively. Results of volatile fractions activity are marked with purple frames. (A,B)—thyme oil (SA 2, SA ATCC 33591, respectively); (C,D)—tea tree oil (SA 35, SA ATCC 33591, respectively); (E,F)—basil oil (SA 32, SA 33, respectively); (G,H)—rosemary oil (SA 33, SA 10, respectively); (I,J)—eucalyptus oil (SA 5, SA 28, respectively); (K,L)—menthol mint oil (SA 33, M SA ATCC 33591, respectively); (M,N)—lavender oil (SA 35, SA 33, respectively); (O,P)—sodium chloride 0.9% (control setting) (SA 26, SA 27, respectively). The picture (F) shows the zone of the partial inhibition of growth.
