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 ... -
Biofiltration of waste gases containing a mixture of formaldehyde and methanol
(Springer, 2004-04)Several biofilters and biotrickling filters were used for the treatment of a mixture of formaldehyde and methanol; and their efficiencies were compared. Results obtained with three different inert filter bed materials (lava ... -
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 ... -
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 ... -
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 ...
