Varela, Patricia; Levicán, Gloria; Rivera, Francisco; Jerez, Carlos A. (1998)Thiobacillus ferrooxidans is one of the chemolithoautotrophic bacteria important in industrial biomining operations. During the process of ore bioleaching, the microorganisms are subjected to several stressing conditions, ...

Poveda, Gabriela; Gil Durán, Carlos; Vaca Cerezo, Inmaculada; Levicán, Gloria; Chávez, Renato (2018)BACKGROUND: Pectinase enzymes catalyze the breakdown of pectin, a key component of the plant cell wall. At industrial level, pectinases are used in diverse applications, especially in food-processing industry. Currently, ...

Del-Cid, Abdiel; Ubilla, Pamela; Ravanal, María Cristina; Medina, Exequiel; Vaca Cerezo, Inmaculada; Levicán, Gloria; Eyzaguirre, Jaime; Chávez, Renato (2014)Despite their potential biotechnological applications, cold-active xylanolytic enzymes have been poorly studied. In this work, 38 fungi isolated from marine sponges collected in King George Island, Antarctica, were screened ...

Espinosa, Yeison; Trebotich, Jovanka; Sepúlveda, Francisco; Cadena, Jeisson; Vargas Straube, María José; Vaca Cerezo, Inmaculada; Bull, Paulina; Levicán, Gloria; Chávez, Renato (Springer, 2011)The biotechnological applications of cheese-ripening fungi have been limited by a lack of genetics tools, in particular the identification and characterization of suitable promoters for protein expression. In this study, ...

Levicán, Gloria; Katz, Assaf; De Armas, Merly; Núñez, Harold; Orellana, Omar (2007)Glutamyl-tRNA (Glu-tRNA), formed by Glu-tRNA synthetase (GluRS), is a substrate for protein biosynthesis and tetrapyrrole formation by the C 5 pathway. In this route Glu-tRMA is transformed to δ-aminolevulinic acid, the ...
