Fonseca, María Isabel; Fariña, Julia Ines; Sadañoski, Marcela Alejandra; D'Errico, Roger; Villalba, Laura Lidia; Zapata, Pedro Darío (Elsevier, 2015-10-01)In this work we evaluated the decolorization ability of fungus identified as Phlebia brevispora BAFC 633 on Kraft liquor effluents and we looked at the biochemical characterization of two novel laccases from the fungus. ... -
Effect of wood flour as carbon source on cellulases and xylanases production by white-rot-fungi native from Misiones
Rodríguez, María Daniela; Barchuk, Mónica Lucrecia; Fonseca, María Isabel; Zapata, Pedro Darío; Villalba, Laura Lidia (Council for Innovative Research, 2015-11-10)There is a need to explore lignocellulosic materials to select an adequate substrate for lignocellulolytic enzyme production. Utilization of some residues provides an opportunity to produce high yields of lignocellulolytic ... -
Evaluation of rice by-products, incubation time, and photoperiod for solid state mass multiplication of the biocontrol agents Beauveria bassiana and Metarhizium anisopliae
Bich, Gustavo Ángel; Castrillo, María Lorena; Villalba, Laura Lidia; Zapata, Pedro Darío (Estonian Agricultural University, 2018-08-01)The success of biological control of insect pests depends not only on the isolation, characterization, and pathogenicity, but also on the success of the mass production of the microbial agents. The biological control ... -
Evaluation of synthetic and semi- synthetic culture media for endo-1,4-β- glucanases secretion by trichoderma koningiopsis
Castrillo, María Lorena; Bich, Gustavo Ángel; Kramer, Gustavo Raúl; Velázquez, Juan Ernesto; Rodríguez, María Daniela; Zapata, Pedro Darío; Villalba, Laura Lidia (Elsevier, 2015-06-01)The actual demand of energy and the environmental concerns together with the reduced fossil fuel reserves have played an important role to convert the second generation bioethanol production into an attractive research ... -
First whole-genome shotgun sequence of a promising cellulase secretor, Trichoderma koningiopsis Strain POS7
Castrillo, María Lorena; Bich, Gustavo Ángel; Modenutti, Carlos Pablo; Turjanski, Adrián; Zapata, Pedro Darío; Villalba, Laura Lidia (American Society for Microbiology, 2017-09-14)Trichoderma koningiopsis strain POS7 produces significantly large amounts of cellulase enzymes in solid-state fermentation. The Illumina-based sequence analysis reveals an approximate genome size of 36.6 Mbp, with a G+C ... -
