Simultaneous removal of 2-chlorophenol, phenol, p-cresol and p-hydroxybenzaldehyde under nitrifying conditions: Kinetic study

Catabolism of Phenol and Its Derivatives in Bacteria

“…Such a mixture containing ammonium and several phenolic compounds (phenol, 2-chlorophenol, 4-cresol, and 4-hydroxybenzaldehyde) was efficiently treated with a nitrifying sludge microbial community in a 5-L continuously stirred tank reactor (Silva, Gomez, & Beristain-Cardoso, 2011). This nitrifying microbial consortium removed all phenolic compounds of the mixture completely.…”

Simultaneous oxidation of ammonium and cresol isomers in a sequencing batch reactor: physiological and kinetic study

“…Because of their complex chemical composition, these wastewaters represent a great challenge for their disposal and treatment (Silva et al 2011). Actually, there is a growing interest to develop technologies for the biological treatment of effluents containing ammonium and phenolic compounds (Jemaat et al 2013(Jemaat et al , 2014.…”

“…Responsible editor: Gerald Thouand * Anne-Claire Texier texierac@yahoo.fr In the literature, there are various studies on the inhibitory effects of phenolic compounds on nitrification and at the same time, on the metabolic ability of nitrifying consortia for oxidizing these aromatic compounds: phenol (Yamagishi et al 2001;Amor et al 2005;Silva et al 2011), o-cresol (Jemaat et al 2014), p-cresol Beristain-Cardoso et al 2011), 2-chlorophenol (Martínez-Hernández et al 2011;Pérez-Alfaro et al 2013), p-hydroxybenzaldehyde (Téllez-Pérez et al 2013), and p-nitrophenol (Jemaat et al 2013). Most of these studies were focused on the simultaneous elimination of ammonium and a unique phenolic compound and the information on the simultaneous oxidation of mixtures of ammonium and diverse phenolic compounds is still limited, especially in bioreactors.…”

“…Most of these studies were focused on the simultaneous elimination of ammonium and a unique phenolic compound and the information on the simultaneous oxidation of mixtures of ammonium and diverse phenolic compounds is still limited, especially in bioreactors. The study of Silva et al (2011) was performed in batch cultures with 2-chlorophenol, phenol, pcresol, and p-hydroxybenzaldehyde in mixture. These phenolic compounds present different functional groups, and it is well known that the recalcitrance and inhibition effects of phenolic compounds depend on the nature of their functional groups but also on their position (O'Connor and Young 1996).…”

Aerobic biodegradation of a mixture of monosubstituted phenols in a sequencing batch reactor

“…Gallego et al [7] reported the simultaneous biodegradation of phenol, o-chlorophenol and m-cresol in an aerobic fluidized-bed reactor with the biomass supported on activated carbon. Recently, Silva et al [15] reported the simultaneous removal of o-cholorophenol, phenol, p-cresol and p-hydroxybenzaldehyde under nitrifying conditions. In both these studies, high-strength phenolic wastewaters (≈ 200 mg C L -1 ) were treated.…”
