    • Cultivable psychrotolerant yeasts associated with Antarctic marine sponges 
      Vaca Cerezo, Inmaculada; Faúndez, Carolina; Maza, Felipe; Paillavil, Braulio; Hernández, Valentina; Acosta, Fermín; Levicán, Gloria; Martínez, Claudio; Chávez, Renato (Springer, 2013)
      Unlike filamentous fungi and bacteria, very little is known about cultivable yeasts associated with marine sponges, especially those from Antarctic seas. During an expedition to King George Island, in the Antarctica, samples ...
    • Diversity of cultivable fungi associated with Antarctic marine sponges and screening for their antimicrobial, ... 
      Henríquez, Marlene; Vergara, Karen; Norambuena, Javiera; Beiza, Andrea; Maza, Felipe; Ubilla, Pamela; Araya, Ivanna; Chávez, Renato; San Martín Barrientos, Aurelio; Darias, José; Darias, María J.; Vaca Cerezo, Inmaculada (Springer, 2014)
      The diversity of sponge-associated fungi has been poorly investigated in remote geographical areas like Antarctica. In this study, 101 phenotypically different fungal isolates were obtained from 11 sponge samples collected ...
    • Evaluation of properties of several cheese-ripening fungi for potential biotechnological applications 
      Chávez, Renato; Roa, Amanda; Navarrete, Katherinne; Trebotich, Jovanka; Espinosa, Yeison; Vaca Cerezo, Inmaculada (Springer, 2010)
      Strains of Penicillium camemberti and Penicillium roqueforti were tested for properties that could be important for future biotechnological applications of these fungi. Penicillium camemberti CECT 2267 and P. roqueforti NRRL ...
    • Filamentous fungi from extreme environments as a promising source of novel bioactive secondary metabolites 
      Chávez, Renato; Fierro, Francisco; García Rico, Ramón O.; Vaca Cerezo, Inmaculada (Frontiers Media S.A., 2015)
      Natural product search is undergoing resurgence upon the discovery of a huge previously unknown potential for secondary metabolite (SM) production hidden in microbial genomes. This is also the case for filamentous fungi, ...
    • Glucose-induced production of a Penicillium purpurogenum xylanase by Aspergillus nidulans 
      Ravanal, María Cristina; Espinosa, Yeison; Rosa, Lorena; Vaca Cerezo, Inmaculada; Polanco, Rubén; Eyzaguirre, Jaime; Levicán, Gloria; Chávez, Renato (Springer, 2012)
      The heterologous secretion of xylanase B from Penicillium purpurogenum using glucose as inducer was performed in Aspergillus nidulans. For this purpose, plasmid pEVXB, containing the xylanase B cDNA (including its own ...
    • Identification and Functional Analysis of the Mycophenolic Acid Gene Cluster of Penicillium roqueforti 
      Cid, Abdiel del; Gil Durán, Carlos; Vaca Cerezo, Inmaculada; Rojas Aedo, Juan F.; García Rico, Ramón O.; Levicán, Gloria; Chávez, Renato (Public Library Science, 2016)
      The filamentous fungus Penicillium roqueforti is widely known as the ripening agent of blue-veined cheeses. Additionally, this fungus is able to produce several secondary metabolites, including the meroterpenoid compound ...
    • IMA genome-F14 draft genome sequences of penicillium roqueforti, fusarium sororula, chrysoporthe puriensis, ... 
      Van der Nest, Magriet A.; Chávez, Renato; De Vos, Lieschen; Duong, Tuan A.; Gil Durán, Carlos; Ferreira, María Alves; Lane, Frances a.; Levicán, Gloria; Santana, Quentin C.; Steenkamp, Emma T.; Suzuki, Hiroyuki; Tello, Mario; Rakoma, Jostina R.; Vaca Cerezo, Inmaculada; Valdés, Natalia; Wilken, P. Markus; Wingfield, Michael J.; Wingfield, Brenda D. (BMC, 2021)
      Draft genomes of Penicillium roqueforti, Fusarium sororula, Chalaropsis populi, and Chrysoporthe puriensis are presented. Penicillium roqueforti is a model fungus for genetics, physiological and metabolic studies, as well ...
    • Leucosporidium escuderoi f.a., sp. nov., a basidiomycetous yeast associated with an Antarctic marine sponge 
      Laich, Federico; Chávez, Renato; Vaca Cerezo, Inmaculada (Springer, 2014)
      A basidiomycetous yeast, strain E2A-C3- II, was isolated from a marine sponge (Hymeniacidon sp.) collected at a depth of 6 m in Fildes Bay, King George Island, Antarctica. The phylogenetic analysis revealed that the ...
    • The pcz1 Gene, which Encodes a Zn(II)(2)Cys(6) Protein, Is Involved in the Control of Growth, Conidiation, ... 
      Gil Durán, Carlos; Rojas Aedo, Juan F.; Medina, Exequiel; Vaca Cerezo, Inmaculada; García Rico, Ramón O.; Villagrán, Sebastián; Levicán, Gloria; Chávez, Renato (Public Library Science, 2015)
      Proteins containing Zn(II)(2)Cys(6) domains are exclusively found in fungi and yeasts. Genes encoding this class of proteins are broadly distributed in fungi, but few of them have been functionally characterized. In this ...
    • Penicillium chrysogenum, a vintage model with a cutting-edge profile in biotechnology 
      Fierro, Francisco; Vaca Cerezo, Inmaculada; Castillo, Nancy I.; Ovidio García-Rico, Ramón; Chávez, Renato (MDPI, 2022)
      The discovery of penicillin entailed a decisive breakthrough in medicine. No other medical advance has ever had the same impact in the clinical practise. The fungus Penicillium chrysogenum (reclassified as P. rubens) has ...
    • The emergence of new catalytic abilities in an endoxylanase from family GH10 by removing an intrinsically ... 
      Gil Durán, Carlos; Sepúlveda, Romina V.; Rojas, Maximiliano; Castro Fernández, Víctor Hugo; Guixe Leguia, Victoria; Vaca Cerezo, Inmaculada; Levicán, Gloria; González Nilo, Fernando; Ravanal, María Cristina; Chávez, Renato (MDPI, 2022)
      Endoxylanases belonging to family 10 of the glycoside hydrolases (GH10) are versatile in the use of different substrates. Thus, an understanding of the molecular mechanisms underlying substrate specificities could be very ...
