      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 ...
    • 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 ...
    • New butyrolactone from a marine-derived fungus aspergillus SP 
      San Martín Barrientos, Aurelio; Rovirosa, Juana; Vaca Cerezo, Inmaculada; Vergara, Karen; Acevedo, Laura; Viña, Dolores; Orallo, Francisco; Chamy, María Cristina (Sociedad Chilena de Quimica, 2011)
      Four compounds that belong to two structure types, namely dibenzylbutyrolactone and sesterterpenoids, were obtained from the extract of the strain Aspergillus sp. (2P-22), isolated from a marine sponge, Cliona chilensis. ...
    • 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 ...
