The MIC and MTC values were determined based on the average MIC or MTC of 3 separate growth kinetic and were expressed in part per million (ppm or mg/l).
As a control, a solution of Tween (10%; w/w) was assayed and it did not show any growth inhibition against target bacteria. In this study, the results obtained for the PC were used to compare our results with other experiments published in the literature. Each experiment was done in triplicate.
