Draft Genome Sequence of Cellulolytic and Xylanolytic Cellulomonas sp. Strain B6 Isolated from Subtropical Forest Soil
Piccinni, Florencia Elizabeth; Murua, Yanina; Ghio, Silvina; Talia, Paola Mónica; Rivarola, Maximo Lisandro; Campos, Eleonora (2016-08)The genome information will be useful for studies of microbial enzymes for industrial application in lignocellulosic biomass utilization. -
EcXyl43 β-xylosidase: molecular modeling, activity on natural and artificial substrates, and synergism with endoxylanases for lignocellulose deconstruction
Ontañon, Ornella Mailén; Ghio, Silvina; Marrero Diaz De Vill, Rubén; Piccinni, Florencia Elizabeth; Talia, Paola Mónica; Cerutti, Maria Laura; Campos, Eleonora (Springer, 2018-08)Biomass hydrolysis constitutes a bottleneck for the biotransformation of lignocellulosic residues into bioethanol and high-value products. The efficient deconstruction of polysaccharides to fermentable sugars requires ... -
GH10 XynA is the main xylanase identified in the crude enzymatic extract of Paenibacillus sp. A59 when grown on xylan or lignocellulosic biomass
Ghio, Silvina; Insani, Ester Marina; Piccinni, Florencia Elizabeth; Talia, Paola Mónica; Grasso, Daniel Horacio; Campos, Eleonora (2016)A novel bacterial isolate with polysaccharides degrading activity was identified as Paenibacillus sp., andnamed Paenibacillus sp. A59. Even though it is a strict mesophile, optimal xylanase activity of the crudeenzymatic ... -
Insights into the xylan degradation system of Cellulomonas sp. B6 : biochemical characterization of rCsXyn10A and rCsAbf62A
Garrido, Mercedes Maria; Piccinni, Florencia Elizabeth; Landoni, Malena; Peña, María Jesús; Topalian, Juliana; Couto, Alicia; Wirth, Sonia Alejandra; Urbanowicz, Breeanna Rae; Campos, Eleonora (Springer, 2022)Valorization of the hemicellulose fraction of plant biomass is crucial for the sustainability of lignocellulosic biorefineries. The Cellulomonas genus comprises Gram-positive Actinobacteria that degrade cellulose and other ... -
Paenibacillus sp. A59 GH10 and GH11 extracellular endoxylanases: application in biomass bioconversion
Ghio, Silvina; Ontañon, Ornella Mailén; Piccinni, Florencia Elizabeth; Marrero Diaz De Vill, Rubén; Talia, Paola Mónica; Grasso, Daniel Horacio; Campos, Eleonora (Springer, 2018-03)The cost-efficient degradation of xylan to fermentable sugars is of particular interest in second generation bioethanol production, feed, food, and pulp and paper industries. Multiple potentially secreted enzymes involved ... -
Paenibacillus xylanivorans sp. nov., a xylan-degrading bacterium isolated from decaying forest soil
Ghio, Silvina; Sauka, Diego Hernan; Ferrari, Alejandro E.; Piccinni, Florencia Elizabeth; Ontañon, Ornella Mailén; Campos, Eleonora (Microbiology Society, 2019-12)A xylanolytic bacterial strain, named A59T, was isolated from a forest soil consortium in southern Argentina. Strain A59T is a Gram-stain-positive, facultative anaerobic, endospore-forming and rod-shaped bacterium. Its ... -
Secretome profile of Cellulomonas sp. B6 growing on lignocellulosic substrates
Piccinni, Florencia Elizabeth; Ontañon, Ornella Mailén; Ghio, Silvina; Sauka, Diego Hernan; Talia, Paola Mónica; Rivarola, Maximo Lisandro; Valacco, María Pía; Campos, Eleonora (Wiley; Society for Applied Microbiology, 2018-12)Aims: Lignocellulosic biomass deconstruction is a bottleneck for obtaining biofuels and value‐added products. Our main goal was to characterize the secretome of a novel isolate, Cellulomonas sp. B6, when grown on residual ... -
Synergic activity of Cel8Pa β-1,4 endoglucanase and Bg1Pa β-glucosidase from Paenibacillus xylanivorans A59 in beta-glucan conversio
Ghio, Silvina; Bradanini, María B.; Garrido, Mercedes Maria; Ontañon, Ornella Mailen; Piccinni, Florencia Elizabeth; Marrero Diaz De Vill, Rubén; Talia, Paola Mónica; Campos, Eleonora (Elsevier, 2020-12)In the efficient bioconversion of polysaccharides from lignocellulosic biomass, endoglucanases and β-glucosidases are key enzymes for the deconstruction of β-glucans. In this work, we focused on a GH8 endoglucanase ...
