Therefore, the objective of this study is to determine the resistance and tolerance to heavy metals in bacteria under the canopy of resource islands in the Colombian Caribbean. Through a metagenomic approach, genes related to tolerance and resistance to heavy metals were identified in the soil, and it was found that the abundance of these genes was favored by the wet season and the presence of vegetation.Las bacterias de islas de recursos pueden adaptarse a condiciones extremas en regiones semiáridas. Donde además ya han sido encontradas concentraciones de metales pesados en el suelo. Por esto, el objetivo de este trabajo es determinar el potencial resistente y tolerante a metales pesados en bacterias bajo el dosel de islas de recursos en el Caribe colombiano. Mediante un enfoque en metagenómica, se identificaron genes de tolerancia y resistencia a metales pesados en el suelo, encontrando que la abundancia de estos genes se favoreció por la temporada de humedad y la presencia de vegetación.spaAcceso a solo metadatosBioquimica57438.23 H565aTrabajo de grado (Pregrado y/o Especialización)Biochemistryinfo:eu-repo/semantics/closedAccesshttp://purl.org/coar/access_right/c_14cbAbou-Shanab, R.
