Sci Rep
. 2023 Aug;
13(1):13363.
PMID: 37591893
In recent years, the peroxidase enzymes have generated wide interest in several industrial processes, such as wastewater treatments, food processing, pharmaceuticals, and the production of fine chemicals. However, the low...

J Fish Biol
. 2021 Oct;
100(1):150-160.
PMID: 34676538
Fish processing generates plenty of waste that is directly discarded in open-air dumps and water sources, or treated in the same way as urban solid waste, causing serious pollution problems....

Lobo C, Bertola N, Contreras E, Zaritzky N
Environ Sci Pollut Res Int
. 2017 Jul;
25(22):21272-21285.
PMID: 28726229
The aim of this study was to analyze the mechanisms, stoichiometry, and stability of 4-chlorophenol (4CP) biodegradation kinetics by phenol-acclimated activated sludge using open respirometry. While the removal of 4CP...

Lobo C, Bertola N, Contreras E
Bioresour Technol
. 2013 Apr;
136:58-65.
PMID: 23562772
The aerobic degradation of phenol (PH), catechol (CA), resorcinol (RE), pyrogallol (PY), and hydroquinone (HY) by phenol-acclimated activated sludge was investigated. A Haldane-type dependence of the respiration rate on PH,...

J Hazard Mater
. 2008 Mar;
158(2-3):366-74.
PMID: 18328621
In this paper respirometric techniques were used to study the effect of pH, phenol and dissolved oxygen (DO) concentrations on the phenol biodegradation kinetics by activated sludges. In addition, a...

J Hazard Mater
. 2007 Jun;
150(1):46-52.
PMID: 17543453
The combined carbon-activated sludge process has been proposed as an alternative to protect the biomass against toxic substances in wastewaters; however, the information about the effect of powdered-activated carbon (PAC)...

Water Res
. 2004 Jun;
38(11):2621-30.
PMID: 15207592
