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 ...
-
Jerez Guevara, Carlos (Wiley, 2017)Mining activities have been carried out for thousands of years and nowadays have an enormous worldwide use to obtain important metals of industrial use. These include copper, iron, gold and several others. Although modern ...

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 ...
-
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 ...

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 ...

Martínez Bussenius, Cristóbal; Navarro, Claudio A.; Orellana, Luis; Paradela, Alberto; Jerez Guevara, Carlos (2016)Acidithio bacillus ferrooxidans is used in industrial bioleaching of minerals to extract valuable metals. A. ferrooxidans strain ATCC 53993 is much more resistant to copper than other strains of this microorganism and it ...

Orell, Alvaro; Navarro, Claudio A.; Arancibia, Rafaela; Mobarec, Juan C.; Jerez Guevara, Carlos (PERGAMON-ELSEVIER SCIENCE LTD, 2010-07-11)Industrial biomining processes to extract copper, gold and other metals involve the use of extremophiles such as the acidophilic Acidithiobacillus ferrooxidans (Bacteria), and the thermoacidophilic Sulfolobus metallicus ...
-
Martínez Bussenius, Cristóbal; Navarro, Claudio A.; Jerez Guevara, Carlos (Wiley, 2017)Industrial biomining has been extensively used for many years to recover valuable metals such as copper, gold, uranium and others. Furthermore, microorganisms involved in these processes can also be used to bioremediate ...
-
Orell, Álvaro; Remonsellez, Francisco; Arancibia, Rafaela; Jerez Guevara, Carlos (Hindawi, 2013)Sulfolobus metallicus is a thermoacidophilic crenarchaeon used in high-temperature bioleaching processes that is able to grow under stressing conditions such as high concentrations of heavy metals. Nevertheless, the genetic ...

Gordillo, Felipe; Chávez, Francisco P.; Jerez Guevara, Carlos (BLACKWELL, 2007-03-20)The polychlorinated biphenyl (PCB)-degrading Pseudomonas sp. B4 was tested for its motility and ability to sense and respond to biphenyl, its chloroderivatives and chlorobenzoates in chemotaxis assays. Pseudomonas sp. ...

Varela, Cristián; Mauriaca, Cecilia; Paradela, Alberto; Albar, Juan P.; Jerez Guevara, Carlos; Chávez, Francisco P. (2010)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 ...
-
Vera, M.; Guiliani Guerin, Nicolás; Jerez Guevara, Carlos (ELSEVIER, 2003-10)The recent availability of an incomplete genomic sequence from Acidithiobacillus ferrooxidans allowed us to continue and strengthen the demanding task of investigating the proteome and its functional implications in this ...

Leyton, Patricio; Lizama Vergara, P. A.; Campos Vallette, Marcelo; Becker, María Inés; Clavijo Campos, Ernesto; Córdova Reyes, I.; Vera, M.; Jerez Guevara, Carlos (SOCIEDAD CHILENA DE QUIMICA, 2005-12)Surface-enhanced Raman spectroscopy (SERS) was demonstrated to be a useful and sensitive structural spectroscopic tool for the characterization of different types of supramolecular architectures, ideally suited for trace ...
-
Jerez Guevara, Carlos (ELSEVIER, 2008-11)The use of genomics, proteomics, transcriptomics, metabolomics and other OMICs approaches together with bioinformatics tools allows a global picture of how a microbial cell operates in its community to be obtained. The ...
