“…Up to now, several studies have shown that phenol degradation at 55 °C under methanogenic conditions was possible (Karlsson et al, 1999;Fang et al, 2005;Levén et al, 2006;Chen et al, 2008;Limam et al, 2013), but the knowledge regarding the thermophilic phenol metabolic pathway is limited due to the fast degradation rates which hamper metabolite accumulation and pathway elucidation. Nevertheless, today it is generally accepted that thermophilic phenol degradation occurs via caproate (Fang et al, 2005) and not through the benzoic acid pathway, generally used in the mesophilic condition Winter, 1987, 1989;Béchard et al, 1990;Gallert et al, 1991;Karlsson et al, 1999;Levén and Schnürer, 2005;Zhang et al, 2005).…”

Anaerobic digestion makes it possible to valorize municipal solid waste (MSW) into biogas and digestate which are, respectively, a renewable energy source and an organic amendment for soil. Phenols are persistent pollutants present in MSW that can inhibit the anaerobic digestion process and have a toxic effect on microbiota if they are applied to soil together with digestate. It is then important to define the operational conditions of anaerobic digestion which allow the complete degradation of phenol. In this context, the fate of phenol during the anaerobic digestion of MSW at 55°C was followed using an isotopic tracing approach ((13)C6-phenol) in experimental microcosms with inoculum from an industrial thermophilic anaerobic digester. With this approach, it was possible to demonstrate the complete phenol biodegradation into methane and carbon dioxide via benzoate. Benzoate is known to be a phenol metabolite under mesophilic conditions, but in this study it was found for the first time to be a phenol degradation product at thermophilic temperature.

“…Our previous study indicated that acclimation of sludge also influenced the degradation behavior of BPA; mixed liquor suspended solid (MLSS), initial chemical oxygen demand (COD) and temperature influenced BPA sorption onto sludge under aerobic condition. Much research indicated that BPA was hardly degraded under anaerobic conditions. Kang and Kondo found that <10% of BPA decreased in river water samples over 10 days under anaerobic conditions.…”

“…Voordeckers et al 19 and Kang et al 20 found that BPA was not biodegraded even after 3 months of incubation in anaerobic marine sediments. Moreover, Limam et al 21 found that no biodegradation of BPA was observed during municipal solid waste anaerobic digestion. However, Zhou et al 13 recently obtained 90% and 85% BPA elimination by anaerobic and anoxic activated sludge, respectively.…”

BACKGROUND: Bisphenol A (BPA) and 4-n-nonylphenol (4-n-NP) are of significant research interest due to their extensive use and toxicological properties. Batch experiments were conducted to investigate the sorption and degradation behavior of BPA and 4-n-NP using acclimated activated sludge either under anoxic conditions in the presence of nitrate or under anaerobic conditions in the absence of nitrate.

“…Therefore, BPA is frequently found in plastic bottles, food cans, containers, composite dental fillings and adhesives . This compound is not readily biodegradable with common biological methods requiring lengthy treatments; thus, BPA can persist in the environment causing superficial and groundwater contamination. Effective treatments are needed to prevent negative effects on human health and the environment.…”

BACKGROUND: This work reports the kinetic and biodegradability analysis of bisphenol A (BPA) Fenton oxidation. An experimental study was carried out within the variables H 2 O 2 /Fe (II)/BPA in the range 10/3/1 to 50/3/1 and at temperatures of 25-70 ∘ C. Kinetics of the environmental parameters dissolved organic carbon (DOC) and chemical oxygen demand (COD) were analysed. RESULTS: The concentration of H 2 O 2 and the temperature have a strong influence on the kinetics of Fenton mineralization of BPA.Working at 70 ∘ C, the measured DOC values matched that calculated using the measured organic acids, which demonstrates that the oxidation reactions proceeded at a sufficient rate to form organic acids. Moreover, as BPA solutions are not easily biodegradable, the biodegradability of the solution during Fenton oxidation was studied by means of respirometry assays, evaluating the short-term biochemical oxygen demand (BOD st )/COD ratio. CONCLUSIONS: The kinetic models proposed are capable of predicting the rate of H 2 O 2 consumption and the oxidation of DOC and COD as a function of the temperature. Under the process conditions tested the treated effluents increased their biodegradability, facilitating compatibility with further biological treatment.
