Partial Nitrification of Wastewater from an Aminoplastic Resin Producing Factory
(IWA Publishing, 2005)Nitrification via nitrite was studied in two aerobic reactors treating wastewater from an aminoplastic resin producing factory at HRT varying between 1.37-1.89 and 2.45-3.63 days. Both reactors were fed with concentrations ... -
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 ... -
Performance of a fungal monolith bioreactor for the removal of styrene from polluted air
(Elsevier, 2010-04)Gas-phase styrene removal using the fungus, Sporothrix variecibatus was evaluated in a novel monolith bioreactor, receiving a continuous supply of nutrients from the trickling liquid phase. During the start-up process, ... -
Performance optimization of the fungal biodegradation of α-pinene in gas-phase biofilter
(Elsevier, 2006-08)A Ophiostoma species using α-pinene as the sole source of carbon and energy converted it into biomass, carbon dioxide and water. The strain was inoculated in a biofilter fed α-pinene polluted air, and it remained the ... -
Phenol biodegradation and its effect on the nitrification process
(Elsevier, 2005-08)Phenol biodegradation under aerobic conditions and its effect on the nitrification process were studied, first in batch assays and then in an activated sludge reactor. In batch assays, phenol was completely biodegraded at ... -
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 ... -
Production of biofuels from C1-gases with Clostridium and related bacteria—Recent advances
(Wiley, 2023)[Abstract] Clostridium spp. are suitable for the bioconversion of C1-gases (e.g., CO2, CO and syngas) into different bioproducts. These products can be used as biofuels and are reviewed here, focusing on ethanol, butanol ... -
Production of Short-Chain Fatty Acids (Scfas) As Chemicals or Substrates for Microbes to Obtain Biochemicals
(Springer, 2023-06-03)[Abstract] Carboxylic acids have become interesting platform molecules in the last years due to their versatility to act as carbon sources for different microorganisms or as precursors for the chemical industry. Among ... -
Reactor Designs and Configurations for Biological and Bioelectrochemical C1 Gas Conversion: A Review
(MDPI, 2021-11-07)[Abstract] Microbial C1 gas conversion technologies have developed into a potentially promising technology for converting waste gases (CO2, CO) into chemicals, fuels, and other materials. However, the mass transfer constraint ... -
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 ... -
Removal of dichloromethane from waste gases in one- and two-liquid-phase stirred tank bioreactors and biotrickling filters
(Elsevier, 2009-01)The removal of dichloromethane (DCM) from polluted air was studied both in biotrickling filters and in continuous stirred tank bioreactors, using either a single-liquid aqueous phase or a combination of an aqueous–organic ... -
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 ... -
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 ... -
