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 ... -
Simultaneous nitrification and formaldehyde biodegradation in an activated sludge unit
(Elsevier Sciencie lted, 2005-11)The simultaneous removal of formaldehyde and ammonium in a lab-scale activated sludge unit was investigated. The unit was operated at a hydraulic retention time of 2.4 days with an ammonium concentration in the influent ... -
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 ... -
Styrene removal from polluted air in one and two-liquid phase biotrickling filter: Steady and transient-state performance and pressure drop control
(Elsevier, 2011-07)A Sporothrix variecibatus-inoculated biotrickling filter (BTF) was examined for styrene removal, without and with the addition of silicone oil, at different empty bed residence times. The highest elimination capacities ... -
The SHARON process in the treatment of landfill leachate
(IWA Publishing, 2010)The purpose of this paper was to study the partial nitrification of the nitrogen present in a landfill leachate applying the SHARON process in order to obtain a suitable effluent to the ANAMMOX process. As a first step, ... -
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 ... -
Treatment of slaughterhouse wastewater in a UASB reactor and an anaerobic filter
(Elsevier, 1997-06)A study was performed to assess the feasibility of anaerobic treatment of slaughterhouse wastewaters in a UASB (Upflow Anaerobic Sludge Blanket) reactor and in an AF (Anaerobic Filter). Among the different streams generated, ... -
Treatment of waste gas contaminated with dichloromethane using photocatalytic oxidation, biodegradation and their combinations
(Elsevier, 2020-08-22)[Abstract] The treatment of waste gas (WG) containing dichloromethane (DCM) using advanced oxidation processes (AOPs) [UV and UV-TiO2], biological treatment (BT), and their combination (AOPs-BT) was tested. AOP tests were ... -
Trophic relationships between Saccharomyces cerevisiae and Lactobacillus plantarum and their metabolism of glucose and citrate
(ASM, 1991-04)Glucose and citrate are two major carbon sources in fruits or fruit juices such as orange juice. Their metabolism and the microorganisms involved in their degradation were studied by inoculating with an aliquot of fermented ... -
Two-liquid-phase mesophilic and thermophilic biotrickling filters for the biodegradation of α-pinene
(Elsevier, 2010-12)α-Pinene biodegradation was evaluated in mesophilic and thermophilic biotrickling filters. The potential of silicone oil for enhancing the removal was evaluated too, at both temperatures. Performance was studied at empty ... -
Two‐stage gas‐phase bioreactor for the combined removal of hydrogen sulphide, methanol and α‐pinene
(Taylor & Francis, 2009)Biological treatment systems have emerged as cost‐effective and eco‐friendly techniques for treating waste gases from process industries at moderately high gas flow rates and low pollutant concentrations. In this study, ... -
Use of Styrene as Sole Carbon Source by the Fungus Exophiala oligosperma: Optimization and Modeling of Biodegradation, Pathway Elucidation, and Cell Membrane Composition
(Springer, 2012-11)Biodegradation of styrene by Exophiala sp. was tested at different initial concentrations (19.3–170.6 mg l−1), pH (2.8–8.7), and temperatures (19.8–45.1 °C), for 120 h according to a 23 full-factorial central composite ... -
Valuable product production from wood mill effluents
(IWA Publishing, 2010)Fibreboard production is one of the most important industrial activities in Galicia (Spain). Great amounts of wastewater are generated, with properties depending on the type of wood, treatment process, final product and ...
