Análisis y caracterización de poblaciones bacterianas solubilizadoras de P en un ensayo de larga duración con diferentes secuencias de cultivo
(Asociación Argentina de Ecología, 2023-02-12)Se conoce bien que diferentes sistemas de uso y manejos de suelos afectan la abundancia, la actividad y la composición de la comunidad microbiana del suelo. En este trabajo se estudió el comportamiento de las poblaciones ... -
Descubren una especie de bacteria que degrada biomasa
(Ediciones INTA, 2019-12)Identificada como Paenibacillus xylanivorans, la cepa xilanolítica A59T fue aislada en suelos de bosque nativo de la Patagonia, en el sur de la Argentina. Gracias a la secuenciación del ADN, determinaron que tiene la ... -
GH10 XynA is the main xylanase identified in the crude enzymatic extract of Paenibacillus sp. A59 when grown on xylan or lignocellulosic biomass
(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 ... -
Molecular identification of a cyclodextrin glycosyltransferase-producing microorganism and phylogenetic assessment of enzymatic activities
(Academia Brasileira de Ciências, 2019-10)Cyclodextrin glycosyltransferases (CGTases) are important enzymes in the biotechnology field because they catalyze starch conversion into cyclodextrins and linear oligosaccharides, which are used in food, pharmaceutical ... -
No evidence of enemy release in pathogen and microbial communities of comnon wasps [Vespula vulgaris] in their native and introduced range
(2015-03-23)When invasive species move to new environments they typically experience population bottlenecks that limit the probability that pathogens and parasites are also moved. The invasive species may thus be released from biotic ... -
Paenibacillus sp. A59 GH10 and GH11 extracellular endoxylanases: application in biomass bioconversion
(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
(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 ... -
Prospección y caracterización de bacterias celulolíticas y hemicelulolíticas
(Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2018)La prospección de bacterias con capacidad de degradar lignocelulosa permite la identificación de nuevas enzimas con potencial aplicación en numerosos procesos industriales. En este trabajo el objetivo fue la obtención de ... -
Structural and molecular dynamics investigations of ligand stabilization via secondary binding site interactions in Paenibacillus xylanivorans GH11 xylanase
(Elsevier, 2021-03)Glycoside hydrolases (GHs) are essential for plant biomass deconstruction. GH11 family consist of endo-β-1,4-xylanases which hydrolyze xylan, the second most abundant cell wall biopolymer after cellulose, into small ... -
Synergic activity of Cel8Pa β-1,4 endoglucanase and Bg1Pa β-glucosidase from Paenibacillus xylanivorans A59 in beta-glucan conversio
(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 ...
