Antimicrobial activity of soil bacteria against Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus
The emergence of bacterial resistance to various drugs has made the search for new compounds a priority for the treatment of infections. It is estimated that there are between 100 million and 1 billion different types of bacteria with unique functions and roles. In one gram of soil there are million...

| description | The emergence of bacterial resistance to various drugs has made the search for new compounds a priority for the treatment of infections. It is estimated that there are between 100 million and 1 billion different types of bacteria with unique functions and roles. In one gram of soil there are millions of microorganisms that could produce metabolites with potential antimicrobial activity. Most reside in the top 20 cm of the surface horizon, which contains organic matter. Recent studies have focused on bacterial species that release antimicrobial compounds as possible therapeutic drugs to treat infectious diseases. Therefore, the aim of this work was to isolate and characterize antimicrobial-producing soil bacteria. For this study, bacteria present in the soil of Universidad de Investigación de Tecnología Experimental Yachay, were cultured and characterized. Antagonistic assays were performed between the bacterial isolates and Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus. The results obtained show that the metabolites produced by the isolated strains UITEY-030 and UITEY-055 inhibited the growth of Staphylococcus aureus and Escherichia coli strains, respectively. |

Se calcula que hay entre 100 millones a 1.000 millones de tipos diferentes de bacterias con funciones y papeles únicos. En un gramo de suelo existen millones de microorganismos que potencialmente podrían producir metabolitos con actividad antimicrobiana. La mayoría de ellos se encuentra en los 20 cm del horizonte superficial el cual contienen materia orgánica. Estudios recientes se han centrado en las especies bacterianas que liberan compuestos antimicrobianos como posibles fármacos terapéuticos para tratar enfermedades infecciosas. Con este antecedente, el objetivo de este trabajo es aislar y caracterizar las bacterias productoras de antimicrobianos del suelo. Para este estudio se cultivaron y caracterizaron bacterias presentes en el suelo de la Universidad de Investigación de Tecnología Experimental Yachay. Se realizó ensayos antagónicos entre las bacterias aisladas y las especies de bacterias Escherichia coli, Pseudomonas aeruginosa, y Staphylococcus aureus. Los resultados obtenidos demuestran que los metabolitos producidos por las cepas aisladas, UITEY-030 y UITEY-055, inhibieron el crecimiento de las cepas de Staphylococcus aureus y Escherichia coli, respectivamente.Biólogo/aUniversidad de Investigación de Tecnología Experimental YachayZurita Leal, Andrea Cristina2024-05-20T10:56:21Z2024-05-20T10:56:21Z2024-05info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/bachelorThesisapplication/pdfhttp://repositorio.yachaytech.edu.ec/handle/123456789/778enginfo:eu-repo/semantics/openAccessreponame:Repositorio Universidad Yachay Techinstname:Universidad Yachay Techinstacron:Yachay2025-07-08T17:52:29Zoai:repositorio.yachaytech.edu.ec:123456789/778Institucionalhttps://repositorio.yachaytech.edu.ec/Universidad públicahttps://www.yachaytech.edu.ec/https://repositorio.yachaytech.edu.ec/oaiEcuador...opendoar:102842025-07-08T17:52:29falseInstitucionalhttps://repositorio.yachaytech.edu.ec/Universidad públicahttps://www.yachaytech.edu.ec/https://repositorio.yachaytech.edu.ec/oai.Ecuador...opendoar:102842025-07-08T17:52:29Repositorio Universidad Yachay Tech - Universidad Yachay Techfalse |
