Hydrodynamic behaviour and comparison of technologies for the removal of excess biomass in gas-phase biofilters
(Elsevier, 2004)
The hydrodynamic behaviour of a biofilter fed toluene and packed with an inert carrier was evaluated on start-up and after long-term operation, using both methane and styrene as tracers in Residence Time Distribution ...
Inert filter media for the biofiltration of waste gases – characteristics and biomass control
(Springer, 2002)
Soil biofilters and related systems based onthe use of natural filter beds have been usedfor several years for solving specific airpollution problems. Over the past decade,significant improvements have been brought tothese ...
Removal of formaldehyde, methanol, dimethylether and carbon monoxide from waste gases of synthetic resin-producing industries
(Elsevier, 2008-02)
The removal of mixtures of gas-phase pollutants released from formaldehyde- and formaldehyde resin-producing industries was studied in different bioreactor systems. The waste gases contained formaldehyde, methanol, ...
Biological conversion of carbon monoxide: rich syngas or waste gases to bioethanol
(Wiley-Blackwell, 2011)
Bioconversion of syngas/waste gas components to produce ethanol appears to be a promising alternative compared to the existing chemical techniques. Recently, several laboratory-scale studies have demonstrated the use of ...
Carbon monoxide fermentation to ethanol by Clostridium autoethanogenum in a bioreactor with no accumulation of acetic acid
(Elsevier, 2015-06)
[Abstract] Fermentation of CO or syngas offers an attractive route to produce bioethanol. However, during the bioconversion, one of the challenges to overcome is to reduce the production of acetic acid in order to minimize ...
Ethanol and Acetic Acid Production from Carbon Monoxide in a Clostridium Strain in Batch and Continuous Gas-Fed Bioreactors
(Multidisciplinary Digital Publishing Institute, 2015)
The effect of different sources of nitrogen as well as their concentrations on the bioconversion of carbon monoxide to metabolic products such as acetic acid and ethanol by Clostridium autoethanogenum was studied. In a ...
Selective Butanol Production From Carbon Monoxide by an Enriched Anaerobic Culture
(Elsevier, 2021-09-25)
[Abstract] An anaerobic mixed culture able to grow on pure carbon monoxide (CO) as well as syngas (CO, CO2 and H2), that produced unusual high concentrations of butanol, was enriched in a bioreactor with intermittent CO ...
Influence of feedstock mix ratio on microbial dynamics during acidogenic fermentation for polyhydroxyalkanoates production
(Elsevier, 2021-12-01)
[Abstract] The nature of microbial populations plays an essential role in the production of volatile fatty acids (VFA) during acidogenesis, the first stage in polyhydroxyalkanoates (PHA) production using mixed cultures. ...
Polyhydroxyalkanoates Production From Syngas Fermentation Effluents: Effect of Nitrogen Availability
(Elsevier, 2021-10-29)
[Abstract] Syngas fermentation is a promising technology for bioalcohols production even though some produced volatile fatty acids (VFA) may remain unconsumed in the effluent. The present research explored the production ...
Recent Trends in Biogenic Gas, Waste and Wastewater Fermentation [Editorial]
(MDPI, 2022)
[Abstract] In recent years, the optimization of bioprocesses for the removal of pollutants from industrial biogenic gas emissions, waste and wastewater has been the focus of intensive research. Recently developed technologies ...
