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. ...
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 ...
Steady- and transient-state operation of a two-stage bioreactor for the treatment of a gaseous mixture of hydrogen sulphide, methanol and α-pinene
(Wiley-Blackwell, 2010-03)
A two-stage bioreactor, comprising a biotrickling filter (BTF) as the first stage and a biofilter (BF) as the second stage, operated under steady- and transient-state conditions, was tested to remove gas-phase hydrogen ...
