This research aimed to verify the bactericidal action of a bioactive product, the base of the essential oils of the plants Rosemary-pepper (Lippia menosides), and Citronella (Cymbopogon winterianus) on the bacterium Escherichia coli. The work consisted of two stages, the first characterizes the bioactivated and the second of determining its bactericidal concentration. Chromatographic analysis of each oil revealed that the main components are thymol in pepper rosemary (71.5%) and citronellar in citronella grass (44.2%). The second stage consisted of testing the bioactive on E. coli, using 24 concentrations of the product, ranging from 1: 2 to 1: 8,388,608, obtained by microdilution, using a completely randomized design with 3 replications per treatment. The results revealed a percentage of bactericidal efficiency of 100% up to a concentration of 1: 1024. It is concluded that the bioactive studied is an effective product as a bactericide against E. coli, promising further research in the control of this bacterium in water reservoirs as a possible substitute for chlorine.
