Oetiker N, Munoz-Villagran C, Vasquez C, Bravo D, Perez-Donoso J
J Appl Microbiol . 2020 Dec; 131(1):155-168. PMID: 33274558
Aim: Fluorescent semiconductor nanoparticles or quantum dots (QDs) have excellent properties as photosensitizers in photodynamic therapy. This is mainly a consequence of their nanometric size and the generation of light-activated...

Valdivia-Gonzalez M, Diaz-Vasquez W, Ruiz-Leon D, Becerra A, Aguayo D, Perez-Donoso J, et al.
Arch Microbiol . 2017 Oct; 200(2):267-273. PMID: 29022087
The increasing industrial utilization of tellurium has resulted in an important environmental pollution with the soluble, extremely toxic oxyanion tellurite. In this context, the use of microorganisms for detoxifying tellurite...

Sandoval J, Arenas F, Garcia J, Diaz-Vasquez W, Valdivia-Gonzalez M, Sabotier M, et al.
Microbiol Res . 2015 Jul; 177:22-7. PMID: 26211962
Exposure to the tellurium oxyanion tellurite (TeO3(2-)) results in the establishment of an oxidative stress status in most microorganisms. Usually, bacteria growing in the presence of the toxicant turn black...

Gallardo C, Monras J, Plaza D, Collao B, Saona L, Duran-Toro V, et al.
J Biotechnol . 2014 Jul; 187:108-15. PMID: 25064158
Bacterial biosynthesis of nanoparticles represents a green alternative for the production of nanostructures with novel properties. Recently, the importance of antioxidant molecules on the biosynthesis of semiconductor fluorescent nanoparticles (quantum...

Arenas F, Leal C, Pinto C, Arenas-Salinas M, Morales W, Cornejo F, et al.
Biochimie . 2014 Apr; 102:174-82. PMID: 24680738
The dihydrolipoamide dehydrogenase (LpdA) from the tellurite-resistant bacterium Aeromonas caviae ST reduces tellurite to elemental tellurium. To characterize this NADH-dependent activity, the A. caviae lpdA gene was subjected to site-directed...

Swearingen Jr J, Fuentes D, Araya M, Plishker M, Saavedra C, Chasteen T, et al.
Appl Environ Microbiol . 2006 Jan; 72(1):963-7. PMID: 16391146
The ubiE gene of Geobacillus stearothermophilus V, with its own promoter, was cloned and introduced into Escherichia coli. The cloned gene complemented the ubiE gene deficiency of E. coli AN70....

Saavedra C, Encinas M, Araya M, Perez J, Tantalean J, Fuentes D, et al.
Biochimie . 2004 Aug; 86(7):481-5. PMID: 15308337
The cysK gene encoding a cysteine synthase of Geobacillus stearothermophilus V was overexpressed in E. coli and the recombinant protein was purified and characterized. The enzyme is a thermostable homodimer...

Vasquez C, Saavedra C, Loyola C, Araya M, Pichuantes S
Curr Microbiol . 2001 Oct; 43(6):418-23. PMID: 11685509
The nucleotide sequence of a 4,539 bp fragment of Bacillus stearothermophilus V mediating tellurite resistance in Escherichia coli was determined. Four ORFs of more than 150 amino acids encoding polypeptides...

Vasquez C, Saavedra C, Pichuantes S
Curr Microbiol . 1999 Dec; 40(2):114-8. PMID: 10594225
The nucleotide sequence of a 2837-base pairs (bp) EcoRI-PvuI fragment of Bacillus stearothermophilus LV chromosomal DNA encoding the bstLVIM gene was determined. It revealed a large open reading frame (ORF)...

Vasquez C, Mora G
Arch Biol Med Exp . 1979 Oct; 12(3):367-72. PMID: 552819
Two types of cytoplasmic ribosomes of Euglena gracilis have been found when the stability in vitro of the large subunit at 25 degrees C for 30 min has been considered....
