Anaerobic RSH-dependent tellurite reduction contributes to Escherichia coli tolerance against tellurite

Autor: P. Muñoz-Diaz, K. Jiménez, R. Luraschi, F. Cornejo, M. Figueroa, C. Vera, A. Rivas-Pardo, J. M. Sandoval, C. Vásquez, F. Arenas

Publikováno v: Biological Research, Vol 55, Iss 1, Pp 1-10 (2022)

Abstract Background Tellurium is a rare metalloid that exerts high toxicity on cells, especially on bacteria, partly due to reactive oxygen species (ROS) generation. Moreover, it has also been observed that tellurite can target free cell thiols group

Publikováno v: Microbial Cell Factories, Vol 16, Iss 1, Pp 1-17 (2017)

Abstract Background Bacteria have developed different mechanisms for the transformation of metalloid oxyanions to non-toxic chemical forms. A number of bacterial isolates so far obtained in axenic culture has shown the ability to bioreduce selenite a

Flavoprotein-mediated tellurite reduction: structural basis and applications to the synthesis of tellurium-containing nanostructures

Autor: Mauricio Arenas-Salinas, Joaquín Ignacio Vargas, Wladimir Morales, Camilo Pinto, Pablo Muñoz, Fabian Alexis Cornejo, Benoit Pugin, Juan Sandoval, Waldo Diaz, Claudia Muñoz-Villagrán, Fernanda Jimena Rodríguez, Eduardo Morales, Claudio Christian Vásquez, Felipe Arenas

Publikováno v: Frontiers in Microbiology, Vol 7 (2016)

The tellurium oxyanion tellurite (TeO32-) is extremely harmful for most organisms. It has been suggested that a potential bacterial tellurite resistance mechanism would consist of an enzymatic, NAD(P)H-dependent, reduction to the less toxic form elem

Formation of Se(0), Te(0), and Se(0)–Te(0) nanostructures during simultaneous bioreduction of selenite and tellurite in a UASB reactor

Autor: Shrutika L. Wadgaonkar, Joyabrata Mal, Neeraj Maheshwari, Giovanni Esposito, Piet N.L. Lens, Yarlagadda V. Nancharaiah

Publikováno v: Applied Microbiology and Biotechnology. 102:2899-2911

Simultaneous removal of selenite and tellurite from synthetic wastewater was achieved through microbial reduction in a lab-scale upflow anaerobic sludge blanket reactor operated with 12 h hydraulic retention time at 30 °C and pH 7 for 120 days. Lact
