Identification of the Phenol Functionality in Deprotonated Monomeric and Dimeric Lignin Degradation Products via Tandem Mass Spectrometry Based on Ion-Molecule Reactions with Diethylmethoxyborane.

Hanyu Zhu et al.

Journal of the American Society for Mass Spectrometry, 27(11), 1813-1823 (2016-08-25)

Conversion of lignin into smaller molecules provides a promising alternate and sustainable source for the valuable chemicals currently derived from crude oil. Better understanding of the chemical composition of the resulting product mixtures is essential for the optimization of such

A promiscuous cytochrome P450 aromatic O-demethylase for lignin bioconversion.

Sam J B Mallinson et al.

Nature communications, 9(1), 2487-2487 (2018-06-29)

Microbial aromatic catabolism offers a promising approach to convert lignin, a vast source of renewable carbon, into useful products. Aryl-O-demethylation is an essential biochemical reaction to ultimately catabolize coniferyl and sinapyl lignin-derived aromatic compounds, and is often a key bottleneck

Synthesis, spectroscopy and antimicrobial activity of iron complexes of some smoke flavour compounds.

Meyyappan Arumugam et al.

Natural product research, 26(20), 1942-1944 (2011-10-01)

Iron (III) complexes of some smoke flavour compounds (2-allyloxyphenol, guaiacol, eugenol and 2-ethoxyphenol) were synthesised and characterised by UV-Vis spectroscopy and ESI mass spectrometry. The ligand metal binding ratio was found to be 1:1 by the Job plot method. Antimicrobial

Cellular apoptosis and cytotoxicity of phenolic compounds: a quantitative structure-activity relationship study.

Cynthia D Selassie et al.

Journal of medicinal chemistry, 48(23), 7234-7242 (2005-11-11)

In this comprehensive study on the caspase-mediated apoptosis-inducing effect of 51 substituted phenols in a murine leukemia cell line (L1210), we determined the concentrations needed to induce caspase activity by 50% (I50) and utilized these data to develop the following

Prediction model based on decision tree analysis for laccase mediators.

Fabiola Medina et al.

Enzyme and microbial technology, 52(1), 68-76 (2012-12-04)

A Structure Activity Relationship (SAR) study for laccase mediator systems was performed in order to correctly classify different natural phenolic mediators. Decision tree (DT) classification models with a set of five quantum-chemical calculated molecular descriptors were used. These descriptors included

Mechanism-based irreversible inactivation of horseradish peroxidase at 500 MPa.

Avelina Fernández García et al.

Biotechnology progress, 18(5), 1076-1081 (2002-10-05)

The effects of high-pressure treatment on the reaction rates of horseradish peroxidase (HRP) with guaethol or guaiacol as a hydrogen donor were evaluated from direct transmission measurements in a high-pressure optical cell at 435 nm. Peroxidases are known to be

Two independently regulated cytochromes P-450 in a Rhodococcus rhodochrous strain that degrades 2-ethoxyphenol and 4-methoxybenzoate.

U Karlson et al.

Journal of bacteriology, 175(5), 1467-1474 (1993-03-01)

A red-pigmented coryneform bacterium, identified as Rhodococcus rhodochrous strain 116, that grew on 2-ethoxyphenol and 4-methoxybenzoate as sole carbon and energy sources was isolated. Phylogenetic analysis based on the 16S rDNA sequences indicates that the strain clusters more closely to
