Immobilization of laccase from Cerrena unicolor on controlled porosity glass

Journal of Molecular Catalysis B: Enzymatic, 1999
White-rot basidiomycete Cerrena unicolor grown in non-induced and induced conditions was tested for production of laccase, lignin peroxidase (LiP) and manganese-dependent peroxidase (MnP). A typical correlation between the concentration of phenolic compounds in the culture fluid and the extracellular laccase activity was observed.

Effective Purification of Cerrena unicolor Laccase Using Microfiltration, Ultrafiltration and Acetone Precipitation

Applied Biochemistry and Biotechnology, 2009
Microfiltration followed by concentration and diafiltration on ultrafiltration membranes (Biomax-100, Biomax-10 and Ultracel-10) was used to recover extracellular laccase (EC 1.10.3.2) from culture broth of wood-rotting fungus Cerrena unicolor.

Kinetics of the enzymatic decolorization of textile dyes by laccase from Cerrena unicolor

Dyes and Pigments, 2008
Abstract This study deals with the laccase-catalyzed decolorization of azo and anthraquinone dyes. Both purified laccase (Lacc I and Lacc II) as well as the crude enzyme from the white-rot fungus Cerrena unicolor were used to convert the dyes at pH 3.5 (optimum of laccase activity) in aqueous solution.

Fungus Cerrena unicolor as an effective source of new antiviral, immunomodulatory, and anticancer compounds

International Journal of Biological Macromolecules, 2015
In the report, three bioactive fractions from Cerrena unicolor: laccase (LAC), endopolysaccharides (c-EPL), and low molecular weight (ex-LMS) were tested for the first time towards their antiviral, immunostimulatory, cytotoxic and antiproliferative effect.

Enhancement of laccase production by Cerrena unicolor through fungal interspecies interaction and optimum conditions determination

Archives of Microbiology, 2021
The present study aimed to identify a pair of fungal strains that promote laccase production in the co-cultivation of white-rot basidiomycetes and to determine the optimum conditions to enhance enzyme synthesis under co-fermentation of mandarin peels. Co-cultivation of Cerrena unicolor with Trametes versicolor, Lenzites betulina, and Panus lecomtei led

Transformation of cellobiose during the interaction of cellobiose dehydrogenase and β‐glucosidase of Cerrena unicolor

Journal of Basic Microbiology, 2018
This work investigated the regulatory role of the interaction between cellobiose dehydrogenase (CDH) and β‐glucosidase (β‐GLU) in the conversion of cellobiose into cellobionolactone or glucose in vitro. To study the regulation, the two enzymes were isolated from the culture medium of the fungus Cerrena unicolor grown on a medium with microcrystalline ...

Catalytic behavior and detoxifying ability of a laccase from the fungal strain Cerrena unicolor

Journal of Molecular Catalysis B: Enzymatic, 1998
The kinetics and stability of a laccase isolated and purified from the fungal strain Cerrena unicolor were studied. The enzyme was produced in a great yield without inducers. Kinetic parameters were determined by using 2,2′-azinobis-(3-ethylbenzthiazoline-6-sulfonate) (ABTS) as substrate.

Species-specific Cd-stress Response in the White Rot Basidiomycetes Abortiporus biennis and Cerrena unicolor

Biometals, 2006
The effect of cadmium (Cd) on fungal growth, Cd bioaccumulation and biosorption, and on the formation of potential heavy metal response indicators such as thiols, oxalate, and laccase was investigated in the white rot fungi Cerrena unicolor andAbortiporus biennis. Only the highest Cd concentration employed (200 microM) inhibited growth of C.

Activity of Free and Immobilized ExtracellularCerrena unicolorLaccase in Water Miscible Organic Solvents

Holzforschung, 1998
The extracellular laccase of white rot fungus Cerrena unicolor was purified from culture by ion-exchange chromatography on DEAE-Toyopearl column and immobilized on silanized porous glass beads. During bonding procedure 94.35% protein and 100% laccase activity were coupled to the support.

Two laccase isoforms of the basidiomycete Cerrena unicolor VKMF‐3196. Induction, isolation and properties

Journal of Basic Microbiology, 2010
AbstractThe laccase induction in submerged culture of basidiomycete Cerrena unicolor VKM F‐3196 was investigated. Cu2+ at concentration 0.1 mM was an optimum inducer of C. unicolor laccase. Two isoforms of laccase, namely LacC1 and LacC2, were isolated and characterized.
