Characterizing and Genetically Modifying Oscillatoria to Degrade BPA [PDF]

, 2017
Bisphenol A (BPA) is becoming an increasing environmental concern. It is a hormone disruptor, and its presence in natural waterways causes some aquatic species to experience problems in growth, reproduction, and development.

Laccase production and differential transcription of laccase genes in Cerrena sp. in response to metal ions, aromatic compounds and nutrients

Frontiers in Microbiology, 2016
Laccases can oxidize a wide range of aromatic compounds and are industrially valuable. Laccases often exist in gene families and may differ from each other in expression and function.

Purification and Characterization of a White Laccase with Pronounced Dye Decolorizing Ability and HIV-1 Reverse Transcriptase Inhibitory Activity from Lepista nuda

Molecules, 2016
A strain LN07 with high laccase yield was identified as basidiomycete fungus Lepista nuda from which a white laccase without type I copper was purified and characterized. The laccase was a monomeric protein with a molecular mass of 56 kDa. Its N-terminal

A Sequential Combination of Laccase Pretreatment and Enzymatic Hydrolysis for Glucose Production from Furfural Residues

BioResources, 2014
Furfural residues (FRs) were pretreated with laccase or a laccase-mediator (1-hydroxybenzotriazole, HBT) system to produce fermentable sugar for bioethanol production.

Phenothiazines Rapidly Induce Laccase Expression and Lignin-Degrading Properties in the White-Rot Fungus Phlebia radiata

Journal of Fungi, 2023
Phlebia radiata is a widespread white-rot basidiomycete fungus with significance in diverse biotechnological applications due to its ability to degrade aromatic compounds, xenobiotics, and lignin using an assortment of oxidative enzymes including laccase.

Potential for Ethanol Vapours to Limit Table Grape Berry Shatter and to Limit Ethylene Evolution from Clusters [PDF]

, 2004
We have shown previously that ethanol vapours (given by 2 ml per kg of grapes) can prevent Botrytis development and stem browning, two of the major problems in postharvest quality of table grapes.

Creating Designer Laccases

Chemistry & Biology, 2010
High redox potential laccases from white-rot fungi are recalcitrant to engineering. Maté et al. (2010) employed directed evolution to improve the activity and expression level of the fungal laccase from basidiomycete PM1, followed by rational design to restore thermostability lost during evolution, resulting in a highly active and stable enzyme.

Chemo-Enzymatic Route for Covalent Cellulose Fiber Dyeing. [PDF]

Chemistry
This work presents a proof of concept for a chemo‐enzymatic approach to the covalent dyeing of cotton fibers. Laccase/TEMPO oxidation introduces aldehyde groups, enabling subsequent reductive amination with amino dyes. Excellent color homogeneity and wash fastness were demonstrated using acid red 33, highlighting the robustness of the approach and its ...
