Novel redox-active enzymes for ligninolytic applications revealed from multiomics analyses of Peniophora sp. CBMAI 1063, a laccase hyper-producer strain
(2019-12-01)
The repertoire of redox-active enzymes produced by the marine fungus Peniophora sp. CBMAI 1063, a laccase hyper-producer strain, was characterized by omics analyses. The genome revealed 309 Carbohydrate-Active Enzymes ...
Functionalized hierarchical wrinkled-silica spheres for laccases immobilization
(Springer, 2021-02)
Functionalized mesoporous SiO2 are common supports for some enzymes of industrial interest, such as laccases. However, the incorporation of specific functionalities and the loading of enzymes with dimensions close to the ...
Mycoremediation of high concentrations of polychlorinated biphenyls with Pleurotus sajor-caju LBM 105 as an effective and cheap treatment
(Elsevier, 2019-10-22)
Polychlorinated biphenyls (PCBs) are exceptionally stable organic pollutants. An effective and economically feasible process is essential for their removal. Mycoremediation using white-rot fungal strains proved as a highly ...
Using a mediator system to increase the delignification of sugarcane residues with fungal enzymes
(Universidad Autónoma de Occidente, 2015-12)
Industrial residues are resources that generate regional energy security but they have not been sufficiently
valued. In southern Colombia, the sugar cane sector produces approximately 9´000 000 T/year of
residues, mostly ...
Using a mediator system to increase the delignification of sugarcane residues with fungal enzymes
(Instituto Colombiano del Petróleo (ICP) - ECOPETROL S.A., 2015)
Industrial residues are resources that generate regional energy security but they have not been sufficiently valued. In southern Colombia, the sugar cane sector produces approximately 9´000 000 T/year of residues, mostly ...
Hyperstabilization of a thermophile bacterial laccase and its application for industrial dyes degradation
(Springer, 2020-06)
In the present study, a novel extracellular laccase isolated from Geobacillus stearothermophilus ATCC 10149 was entrapped in a bionanocomposite matrix consisting of copper alginate (Cu-alginate) supplemented with the ...
Tratabilidade de efluente kraft por processo biológico facultativo assistido com enzimas ligninolíticas
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Ciência e Tecnologia AmbientalUTFPR, 2017-03-22)
The kraft process is the most used in the world for the production of pulp and paper. This process was done with high concentrations of organic matter and recalcitrant compounds, which can have a significant impact on the ...
Fast decolorization of azo dyes in alkaline solutions by a thermostable metal‑tolerant bacterial laccase and proposed degradation pathways
(Springer, 2020-07-02)
Biocatalytic decolorization of azo dyes is hampered by their recalcitrance and the characteristics of textile effluents. Alkaline pH and heavy metals present in colored wastewaters generally limit the activity of enzymes ...
Biodegradation of atrazine and ligninolytic enzyme production by basidiomycete strains
(2020-08-26)
Background: Atrazine is one of the most widespread chlorinated herbicides, leaving large bulks in soils and groundwater. The biodegradation of atrazine by bacteria is well described, but many aspects of the fungal metabolism ...
Study of the interaction of the oxidoreductase laccase of Pleurotus ostreatus with gold nanoparticles and phenolic compounds through empirical and in silico techniques
(Universidad de los AndesMaestría en Ingeniería QuímicaFacultad de IngenieríaDepartamento de Ingeniería Química y de Alimentos, 2021-08-03)
The evaluation of the interaction of gold nanoparticles and the phenolic compound chlorogenic acid with laccase isoforms produced by the white root fungus P. ostreatus was performed. Key interactions were evaluated both ...
