Optimization of nutrient supply in a downflow gas-phase biofilter packed with an inert carrier
(Springer, 2002-01)
Several methodologies were tested to supply nutrients to a downflow biofilter packed with perlite and used to treat toluene-polluted air. Despite the presence of an inorganic carrier, elimination capacities of up to around ...
Kinetics of inhibition in the biodegradation of monoaromatic hydrocarbons in presence of heavy metals
(Elsevier Sciencie lted, 2001-06)
The toxicity and inhibitory effects of heavy metals such as cadmium, nickel and zinc on alkylbenzene removal were evaluated with a Bacillus strain. The kinetics of alkylbenzene biodegradation with the different heavy metals ...
Biofiltration of waste gases in a reactor with a split-feed
(Wiley-Blackwell, 2003-06)
The efficiency of using different feed strategies was evaluated in the case of a gas-phase biofilter packed with an inert carrier material. During a preliminary control-period, the biofilter was first fed with a single ...
Biofiltration of waste gases with the fungi Exophiala oligosperma and Paecilomyces variotii
(Springer, 2005-06)
Two biofilters fed toluene-polluted air were inoculated with new fungal isolates of either Exophiala oligosperma or Paecilomyces variotii, while a third bioreactor was inoculated with a defined consortium composed of both ...
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 ...
Biodegradation of toluene by the new fungal isolates Paecilomyces variotii and Exophiala oligosperma Biotechnology. 2005;32(1):33-7
(Springer, 2005-02)
Two new fungal strains, namely Paecilomyces variotii and Exophiala oligosperma, were isolated on toluene as the sole carbon and energy source, mineralizing the substrate into carbon dioxide. Fungal strains isolated so far ...
