Chávez, Francisco P.; Gordillo, Felipe; Jerez Guevara, Carlos (PERGAMON-ELSEVIER SCIENCE LTD, 2006-06)Polychlorinated biphenyls (PCBs) are one of the most widely distributed classes of chlorinated chemicals in the environment. For cleanup of large areas of PCB-contaminated environments, bioremediation seems to be a promising ...

Vera, Mario; Pagliai, Fernando; Guiliani Guerin, Nicolás; Jerez Guevara, Carlos (AMER SOC MICROBIOLOGY, 2008-03)The chemolithoautotrophic bacterium Acidithiobacillus ferrooxidans is of great importance in biomining operations. During the bioleaching of ores, microorganisms are subjected to a variety of environmental stresses and ...

Chávez, Francisco P.; Mauriaca, Cecilia; Jerez Guevara, Carlos (BioMed Central, 2009-03-26)Background: Inorganic polyphosphate (polyP), a polymer of tens or hundreds of phosphate residues linked by ATP-like bonds, is found in all organisms and performs a wide variety of functions. PolyP is synthesized in ...

Álvarez Armijo, Sergio Aníbal; Jerez Guevara, Carlos (AMER SOC MICROBIOLOGY, 2004-09)For some bacteria and algae, it has been proposed that inorganic polyphosphates and transport of metal-phosphate complexes could participate in heavy metal tolerance. To test for this possibility in Acidithiobacillus ...

Remonsellez, Francisco; Orell, Alvaro; Jerez Guevara, Carlos (SOC GENERAL MICROBIOLOGY, 2006-01)It has been postulated that inorganic polyphosphate (polyp) and transport of metal-phosphate complexes could participate in heavy metal tolerance in some bacteria. To study if such a system exists in archaea, the presence ...

Navarro, Claudio A.; Bernath, Diego von; Martínez Bussenius, Cristóbal; Castillo Peñaloza, Rodrigo; Jerez Guevara, Carlos (American Society Microbiology, 2016)Acidophilic organisms, such as Acidithiobacillus ferrooxidans, possess high-level resistance to copper and other metals. A. ferrooxidans contains canonical copper resistance determinants present in other bacteria, such ...
-
Almárcegui Zamorano, Rodrigo Javier (Universidad de Chile, 2014)Acidithiobacillus ferrooxidans es una bacteria extremófila de gran importancia industrial debido a su participación en la recuperación de metales como cobre, oro y uranio en biominería. Esta bacteria puede resistir altas ...

Soto, Daniela F.; Recalde, Alejandra; Orell, Alvaro; Albers, Sonja Verena; Paradela, Alberto; Navarro, Claudio A.; Jerez Guevara, Carlos (Elsevier, 2019)Inorganic polyphosphates (polyP) are present in all living cells and several important functions have been de-scribed for them. They are involved in the response to stress conditions, such as nutrient depletion, oxidativestress ...
