Benzotriazole (BT) is a corrosion inhibitor widely distributed in aquatic environments and one of the most recalcitrant emerging organic contaminants (EOCs) during the biological treatment of wastewater. Recently, microbial cometabolism has been reported as crucial for the biotransformation of EOCs. Cometabolism was described as the transformation of non-growth substrate in...
Se estudió la biocompatibilidad de dos líquidos iónicos, sobre la cepa Escherichia coli TOP10 pQR239, la cual expresa la enzima recombinante ciclohexanona monooxigenasa. Se utilizaron dos líquidos iónicos: (Trioctilmetilamonio bis[(trifluorometil)sulfonil] imida [OMA][BTA] y Butilmetilpirrolidinium bis[(trifluorometil)sulfonil]imida) [MeBuPyrr][BTA]. Se encontró que el líquido iónico [OMA][BTA] resultó ser significativamente más biocompatible que el...
En este trabajo se obtuvo con éxito la bioconversión de naringenina bioactiva para la producción de compuestos de mayor valor agregado en cultivo superficial y líquido. Este enfoque es una alternativa a la producción comercial de estos compuestos bioactivos a partir de fuentes vegetales y principalmente de frutas cítricas, que...
In this study hydroxycinnamic acids were biotransformed. These acids are present in mexican agricultural by-products such as coffee pulp. In order to fulfill this study, moulds from the Universidad Autónoma Metropolitana Iztapalapa (UAMI) and from the Institut de Recherche pour le Développement (IRD) were used. These strains were isolated from...
The emerging organic contaminants (EOCs) comprise a broad set of compounds that include metabolites and transformation products, present in the environment in amounts of ng to mg. Within the EOCs, there are drugs, personal care products, pesticides, etc. More than half of the antibiotics produced worldwide are beta-lactams and many...
