Campo eléctrico aplicado en el periodo de incubación de bacterias

Abstract

Abstract:The general objective of this research work was to determine the effects that the electric field produces in bacteria, in this case E. coli, during its incubation period. The experimental model consisted of cultivating 4 Petri dishes in duplicate, with Escherichia Coli bacterium strains, which were subjected to three different electric fields originated by a direct voltage source and one was cultivated under normal conditions in the incubator at 37°C. (reference box). The boxes planted with the strain were placed on a constant heating plate at 37°C, in the middle of two bases, one upper and one lower, in which aluminum tape electrodes are used, the potential difference at which submits the sample is 100V, 200V and 338V, which was verified with a multimeter. The observations were made every 6 hours until reaching 24 hours, which was when the following results were obtained; Petri dish No. 1 to which 100V was applied did not show any variation, that is, its growth was normal; petri dish No. 2 showed little inhibition after 24 hours and finally petri dish No. 3 had 100% inhibition. Thus demonstrating that the application of an electric field at a certain voltage is effective in eradicating the proliferation of bacteria under normal temperature conditions.
