Biofilter performance and characterization of a biocatalyst degrading alkylbenzene gases
(2009-06)A biofilter treating alkylbenzene vapors was characterized for its optimal running conditions and kinetic parame-ters. Kinetics of the continuous biofilter were compared to batch kinetic data obtained with biofilm samples ... -
Biological conversion of carbon monoxide to ethanol: Effect of pH, gas pressure, reducing agent and yeast extract
(Elsevier, 2012-06)A two-level full factorial design was carried out in order to investigate the effect of four factors on the bioconversion of carbon monoxide to ethanol and acetic acid by Clostridium autoethanogenum: initial pH (4.75–5.75), ... -
Bioprocesses for resource recovery from waste gases: Current trends and industrial applications
(Elsevier, 2021-12-27)[Abstract] Air pollution is a topic of important global concern because it has contributed significantly to an increase in the earth's global warming potential and contributed to severe health and environmental impacts. ... -
Development of a Novel Monolith-Bioreactor for the Treatment of VOC-polluted Air
(Taylor & Francis, 2006)A novel bioreactor packed with ceramic monolith colonized by a toluene-degrading culture was investigated in order to assess its suitability for waste gas treatment. Operational parameters that were considered included ... -
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. ... -
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 ... -
Experimental and neural model analysis of styrene removal from polluted air in a biofilter
(Wiley-Blackwell, 2009-07)BACKGROUND: Biofilters are efficient systems for treating malodorous emissions. The mechanism involved during pollutant transfer and subsequent biotransformation within a biofilm is a complex process. The use of artificial ... -
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, ... -
Removal of methanol from air in a low-pH trickling monolith bioreactor
(Elsevier, 2008-09)A novel ceramic monolith bioreactor colonized by a methanol-degrading culture was investigated in order to assess its suitability for waste gas treatment. The acidotolerant yeast Candida boidinii was identified as dominant ...
