Abstract
La contaminación por metaloides tales como el teluro y el arsénico se ha convertido en un serio problema medioambiental y de salud pública en los últimos años. Por un lado, el teluro es un elemento estratégico para la industria tecnológica actualmente debido a su escasez en la corteza terrestre y al aumento de su demanda para la fabricación de paneles fotovoltaicos. Por ello, es necesario el estudio y desarrollo de estrategias sostenibles para la biodetección, biorreciclaje y biorremediación de ambos metaloides. Debido a su gran versatilidad metabólica, capacidad de adaptación a ambientes extremos y facilidad de manejo en el laboratorio, las bacterias se están utilizando para el estudio y desarrollo de nuevas estrategias y herramientas de eliminación de contaminantes metálicos tales como el telurito y el arsenito. A pesar de los avances en la identificación de los determinantes génicos responsables de la resistencia a metaloides, así como de las rutas de transformación e interacción con éstos, aún queda mucho por conocer a este respecto...
The contamination caused by metalloids like tellurium and arsenic has emerged as a serious environmental and public health issue in recent years. On another front, tellurium has become a strategic element for current technological industries due to its scarcity in the Earth's crust and the increased demand for manufacturing photovoltaic panels. Therefore, studying and developing sustainable strategies for the biodetection, biorecycling, and bioremediation of both metalloids is imperative. Bacteria, owing to their metabolic versatility, adaptability to extreme environments, and ease of handling in laboratories, are being employed to explore and develop new strategies and tools for eliminating metallic contaminants such as tellurite and arsenite. Despite advancements in identifying the genetic determinants responsible for metalloid resistance, as well as in understanding the transformation routes and interaction with these compounds, there is still much to uncover in this field...
