Electrochemical incineration of cresols: A comparative study between PbO2 and boron-doped diamond anodes [PDF]

open access: yes, 2009
The electrooxidation of aqueous solutions containing 5 mM of o-, m- and p-cresol at pH 4.0 has been investigated using a flow filter-press reactor with a boron-doped diamond (BDD) under galvanostatic electrolysis. All cresols are degraded at similar rate

p-cresol methylhydroxylase from a denitrifying bacterium involved in anaerobic degradation of p-cresol

open access: yesJournal of Bacteriology, 1991
A bacterium, strain PC-07, previously isolated as part of a coculture capable of growing on p-cresol under anaerobic conditions with nitrate as the acceptor was identified as an Achromobacter sp. The first enzyme of the pathway, p-cresol methylhydroxylase, which converts its substrate into p-hydroxybenzyl alcohol, was purified.

Gravid females of the mosquito Aedes aegypti avoid oviposition on m-cresol in the presence of the deterrent isomer p-cresol

open access: yesParasites & Vectors, 2014
Background p-cresol (4-methylphenol) and its isomer m-cresol (3-methylphenol) have been shown to activate the same sensilla in Aedes aegypti (Linnaeus) mosquitoes.

Effective p-cresol removal through catalytic liquid-phase oxidation under moderate conditions using Pt/CeO2-ZrO2-SnO2/SBA-16 as a catalyst

open access: yesJournal of Asian Ceramic Societies, 2020
Cresol is among the phenolic compounds that are frequently found in industrial wastewater streams. Most notably, p-cresol has the highest toxicity and the highest permeability effect on skin of all the cresol isomers; hence, wastewater treatment for p ...

Fructooligosaccharide decreases the production of uremic toxin precursor through modulating gut microbes mediated tyrosine metabolism pathway

open access: yesFuture Foods, 2021
Fructooligosaccharide (FOS) is one of the most important and well-known prebiotics that confers health benefits on the host. The effect of FOS is frequently associated with modulation of the abundance of gut microbes.

The analysis of para-cresol production and tolerance in Clostridium difficile 027 and 012 strains

open access: yesBMC Microbiology, 2011
Background Clostridium difficile is the major cause of antibiotic associated diarrhoea and in recent years its increased prevalence has been linked to the emergence of hypervirulent clones such as the PCR-ribotype 027. Characteristically, C.

Primary investigation into the occurrence of Hydroxymethylfurfural (HMF) in a range of smoked products [PDF]

open access: yes, 2018
5-hydroxymethylfurfural (HMF) is produced in foods through many different pathways. Recently, studies have revealed its potential mutagenic and carcinogenic properties.

Identification of phenol- and p-cresol-producing intestinal bacteria by using media supplemented with tyrosine and its metabolites

open access: yesFEMS Microbiology Ecology, 2018
To identify intestinal bacteria that produce phenols (phenol and p-cresol), we screened 153 strains within 152 species in 44 genera by culture-based assay using broth media supplemented with 200 µM each of tyrosine and its predicted microbial metabolic ...

Chemical Metabolomics: Chemical Biology Tools for Advanced Metabolism Investigations

open access: yesAngewandte Chemie, EarlyView.
The human metabolism has been investigated for several millennia. The metabolome is known for a high complexity due to a large number of different metabolites that are present at different concentrations. Metabolomics has been developed as a field to investigate the entire human metabolome and to elucidate disease development mechanisms.
