Whole-cell fungal transformation of precursors into dyes

Microbial Cell Factories, 2010
Background Chemical methods of producing dyes involve extreme temperatures and unsafe toxic compounds. Application of oxidizing enzymes obtained from fungal species, for example laccase, is an alternative to chemical synthesis of dyes.

Purification and Characterization of a Laccase from Cerrena unicolor and Its Reactivity in Lignin Degradation

Bulletin of the Korean Chemical Society, 2002
For efficient biopulping process, very active and stable lignase is essential. Laccase is one of the best enzyme in terms of environmentally benign processes, since the enzyme uses oxygen as an oxidant to degrade lignin and produces no hamful products. We could purify a laccase homogeneously from Cerrena unicolor in a very active state.

Characterization of graphite electrodes modified with laccases from Trametes hirsuta and Cerrena unicolor and their use for flow injection amperometric determination of some phenolic compounds

, 2005
Fungal laccases from Trametes hirsuta and Cerrena unicolor were immobilized on spectroscopic graphite electrodes using physical absorption. The laccase-modified graphite electrodes were mounted as the working electrodes into a wall jet flow through an ...

Production of a high level of laccase by submerged fermentation at 120-L scale of Cerrena unicolor C-139 grown on wheat bran

, 2015
Submerged fermentation in a stirred bioreactor of the white rot fungus Cerrena unicolor C- 139 was done at a 120-L scale in the presence of wheat bran as a cheap lignocellulosic substrate for fungus growth and laccase production. Enzyme monitoring showed

Scale up of Cerrena unicolor Laccase Production

Scale up of Cerrena unicolor Laccase Production
The effect of different carbon source in culture medium of wood–degrading basidiomycete Cerrena unicolor C–139 were investigated. The maximal growth and laccase synthesis in shaken flask was observed in mineral salts broth containing maltose as the carbon source and asparagine as the nitrogen source (C/N=17.45).

Immobilization of laccase on clay minerals as a promising approach to enhance organic carbon sequestration in soils

Бюллетень Почвенного института им. В.В. Докучаева
Understanding the mechanisms underlying the accumulation and stabilization of organic carbon in soils is necessary to preserve and enhance their sequestration potential and to implement sustainable land use practices when converting soils to agricultural

Degradation of a Non-Phenolic β-0-4 Lignin Model Dimer by Cerrena unicolor Laccase and Mediators, Acetovanillone and Acetosyringone

, 2008
This study focuses on the laccase and mediator co-operation in modelling lignin dimer veratrylglycerol-β-vanillate ether (VVE) oxidation. Earlier we stated that constitutive laccase isolated from Cerrena unicolor can cooperate with acetovanillone (AV ...
