    • Cobalamin Protection against Oxidative Stress in the Acidophilic Iron-oxidizing Bacterium Leptospirillum ... 
      Ferrer, Alonso; Rivera, Javier; Zapata, Claudia; Norambuena, Javiera; Sandoval, Álvaro; Chávez, Renato; Levican, Gloria (Frontiers Media, 2016)
      Members of the genus Leptospirillum are aerobic iron-oxidizing bacteria belonging to the phylum Nitrospira. They are important members of microbial communities that catalyze the biomining of sulfidic ores, thereby solubilizing ...
    • Cold-active pectinolytic activity produced by filamentous fungi associated with Antarctic marine sponges 
      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, ...
    • Cold-active xylanase produced by fungi associated with Antarctic marine sponges 
      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 ...
    • Deciphering the role of multiple thioredoxin fold proteins of leptospirillum sp. in oxidative stress tolerance 
      González Aristegui, Daniela; Álamos, Pamela; Rivero, Matías; Orellana Orellana, Omar; Norambuena, Javiera; Chávez, Renato; Levicán, Gloria (MDPI, 2020)
      Thioredoxin fold proteins (TFPs) form a family of diverse proteins involved in thiol/disulfide exchange in cells from all domains of life. Leptospirillum spp. are bioleaching bacteria naturally exposed to extreme conditions ...
    • Heterologous expression, purification and characterization of a highly thermolabile endoxylanase from the ... 
      Gil Durán, Carlos; Ravanal, María Cristina; Ubilla, Pamela; Vaca Cerezo, Inmaculada; Chávez, Renato (Elsevier B.V., 2018)
      © 2018 British Mycological SocietyNumerous endoxylanases from mesophilic fungi have been purified and characterized. However, endoxylanases from cold-adapted fungi, especially those from Antarctica, have been less studied. ...
    • Molecular characterization of the niaD and pyrG genes from Penicillium camemberti, and their use as ... 
      Navarrete, Katherinne; Roa, Amanda; Vaca Cerezo, Inmaculada; Espinosa, Yeison; Navarro, Claudio; Chávez, Renato (BioMed Central Ltd., 2009)
      Genetic manipulation of the filamentous fungus Penicillium camemberti has been limited by a lack of suitable genetics tools for this fungus. In particular, there is no available homologous transformation system. In this ...
    • Production of a heterologous recombinant protein using fragments of the glyceraldehyde-3-phosphate dehydrogenase ... 
      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, ...
    • Role of sfk1 gene in the filamentous fungus Penicillium roqueforti 
      Torrent, Claudia; Gil Durán, Carlos; Rojas Aedo, Juan F.; Medina, Exequiel; Vaca Cerezo, Inmaculada; Castro, Paulo; García Rico, Ramón O.; Cotoras, Milena; Mendoza, Leonora; Levicán, Gloria; Chávez, Renato (Frontiers Media S.A., 2017)
      © 2017 Torrent, Gil-Durán, Rojas-Aedo, Medina, Vaca, Castro, García-Rico, Cotoras, Mendoza, Levicán and Chávez. The sfk1 (suppressor of four kinase) gene has been mainly studied in Saccharomyces cerevisiae, where it was ...
    • The biosynthetic gene cluster for andrastin A in Penicillium roqueforti 
      Rojas Aedo, Juan F.; Gil Durán, Carlos; Del-Cid, Abdiel; Valdés, Natalia; Álamos, Pamela; Vaca Cerezo, Inmaculada; García Rico, Ramón O.; Levicán, Gloria; Tello, Mario; Chávez, Renato (Frontiers Research Foundation, 2017)
      © 2017 Rojas-Aedo, Gil-Durán, Del-Cid, Valdés, álamos, Vaca, García-Rico, Levicán, Tello and Chávez. Penicillium roqueforti is a filamentous fungus involved in the ripening of several kinds of blue cheeses. In addition, ...
