Bioconversion processes
(MDPI, 2018)
Optimization of the landfill leachate treatment by the Fenton process
(Wiley-Blackwell, 2013-03)
The Fenton process was used with the objective of improving the biodegradability of the leachate pretreated biologically up to a value compatible with a subsequent biological treatment. The optimum reaction and settlement ...
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, ...
Biodegradation of gas-phase styrene using the fungus Sporothrix variecibatus: Impact of pollutant load and transient operation
(Elsevier, 2010-03)
Biofiltration of gas-phase styrene was studied using a newly isolated fungus Sporothrix variecibatus, in a perlite biofilter, at inlet concentrations and gas-flow rates ranging from 0.13 to 14 g m−3 and 0.075 to 0.34 m3 ...
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 ...
Characterization of absorbent polymers for the removal of volatile hydrophobic pollutants from air
(Wiley-Blackwell, 2011-01)
An emerging innovation for the treatment of polluted air consists in using a liquid–solid biphasic system, in which the sequestering phase contains inert polymer beads. The different polymers tested here for this purpose ...
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), ...
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, ...
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 ...
