Resumen
Una comparación entre la técnica de espectroscopia de impedancia eléctrica (EIE) y la técnica tradicional de conteo en placa fue realizada para estudiar el crecimiento del Lactobacillus acidophilus (La). Se encontró que, tras la inoculación, y después de 0.8 h, el crecimiento microbiano fue registrado por medio de la EIE, inferida a través del parámetro λ. En contraste, con la técnica de conteo en placa, el mismo parámetro se estimó en 6.8 h. Los datos experimentales obtenidos mediante la EIE fueron ajustados por un circuito RC en serie, posteriormente, las curvas generadas fueron ajustada a los modelos de crecimiento de Gomperte y Boltzmann. Usando écnica de espectroscopia de impedancia eléctrica, la resistencia del medio resultó la más eficiente para la estimación de los parámetros del crecimiento de Lactobacillus acidophilus.
Palabras clave: espectroscopia de impedancia, curva de crecimiento microbiológico, Lactobacillus acidophilus.
Abstract
]]> In this work, a comparison between Impedance Spectroscopy (IS) and Plate Counting to probe the growth of Lactobacillus acidophilus (La) was done. It was found that after inoculation, and after 0.8 h, the microbial growth was noticed by IS, inferred by the λ parameter. In contrast, by means of the Plate Counting method, the growth was noticed after 6.8 h. The experimental data obtained by IS were first fitted by an RC series circuit, and then, the curves generated were modeled by the well-known growing models of Gompertz and Boltzmann. When using the IS technique, it was found that the resistance of the medium was a better parameter to describe the growing process of La.Keywords: impedance spectroscopy, microbiology growing curves, Lactobacillus acidophilus.
