Formaldehyde biodegradation in the presence of methanol under denitrifying conditions
(Wiley-Blackwell, 2006)
Simultaneous formaldehyde and methanol biodegradation and also denitrification were studied in batch assays and in a continuous laboratory-scale reactor. In batch assays, high formaldehyde concentrations (up to 1360 mg ...
Composition and role of extracellular polymers in methanogenic granules
(ASM, 1997-02)
Methanobacterium formicicum and Methanosarcina mazeii are two prevalent species isolated from an anaerobic granular consortium grown on a fatty acid mixture. The extracellular polysaccharides (EPS) were extracted from ...
Combined post-ozonation and biological treatment of recalcitrant wastewater from a resin-producing factory
(Elsevier, 2007-05)
In this study, effluent from the biological treatment of wastewater from a resin-producing factory containing recalcitrant compounds was ozonated under different conditions. Afterwards, the biodegradability of the ozonated ...
Performance of a biofilter for the removal of high concentrations of styrene under steady and non-steady state conditions
(Elsevier, 2009-08-30)
The performance of a laboratory scale perlite biofilter inoculated with a mixed culture was evaluated for gas phase styrene removal under various operating conditions. Experiments were carried out by subjecting the biofilter ...
Combined biological and physicochemical waste-gas cleaning techniques
(Taylor & Francis, 2012-06)
This review presents a general overview of physical, chemical and biological waste-gas treatment techniques such as adsorption, absorption, oxidation and biodegradation, focusing more extensively on combined processes. It ...
Treatment of gas-phase methanol in conventional biofilters packed with lava rock
(Elsevier, 2005-06)
The performance of laboratory scale methanol-degrading biofilters packed with lava rock was checked during almost 1 yr under different conditions. The biomass concentration and biomass adaptation of the inoculum dramatically ...
Formaldehyde biodegradation and its effect on the denitrification process
(Taylor & Francis, 2007)
Simultaneous formaldehyde biodegradation and denitrification in batch assays and in a continuous lab-scale reactor were studied. In batch assays, initial biodegradation rates between 0.7 and 3.3 g CH2O g VSS-1 d-1 were ...
Effect of key parameters on the removal of formaldehyde and methanol in gas-phase biotrickling filters
(Elsevier, 2006-12)
The effect of some important operation parameters, as pH, pollutant load and composition of the nutrient media, on the biodegradation of a mixture of formaldehyde and methanol in a gas-phase biotrickling filter was studied. ...
Energía y sostenibilidad : incidencia en el medio marino
(Netbiblo, 2003)
[Resumen] En un momento en el que la preocupacion mundial por la sostenibilidad del planeta esta presente ya de forma permanente en todos los foros, es importante reflexionar sobre cuales son las ideas fundamentales en las ...
Effect of Endogenous and Exogenous Butyric Acid on Butanol Production From CO by Enriched Clostridia
(Frontiers, 2022-02-16)
[Abstract] Butanol is a potential renewable fuel. To increase the selectivity for butanol during CO fermentation, exogenous acetic acid and ethanol, exogenous butyric acid or endogenous butyric acid from glucose fermentation ...
