Resumen

Streptomyces es reconocido por su capacidad de producir compuestos bioactivos con acción antimicrobiana. Este estudio evaluó la actividad de metabolitos de Streptomyces sp. frente a cepas clínicas de Staphylococcus aureus. El extracto se obtuvo mediante fermentación sumergida, seguida de ensayos de actividad antimicrobiana, difusión en agar y determinación de la Concentración Inhibitoria Mínima (CIM) y la Concentración Bactericida Mínima (CBM). Se evaluaron las cepas estándar ATCC 25923, ATCC 29213 y la cepa clínica IC 2141. El extracto presentó halos de inhibición que variaron entre 17 ± 0,82 mm y 19,33 ± 1,15 mm. Los análisis de CIM y CBM revelaron una actividad inhibitoria y bactericida significativa, destacándose la cepa IC 2141 (CIM y CBM de 625 µg/mL). Los resultados demuestran que Streptomyces produce metabolitos con potencial antibacteriano, incluso contra cepas resistentes a antibióticos convencionales. Se concluye que las actinobacterias representan una fuente prometedora de compuestos bioactivos, reforzando la importancia de la bioprospección microbiana en el desarrollo de alternativas terapéuticas.
