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 ...
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 ...
Biological treatment of industrial wastewater containing formaldehyde and formic acid.
(South African Water Research Comission, 2006-01)
The biological treatment of wastewater from an aminoplastic resin-producing industry was studied in a pre-denitrifica- tion system. This study reports results on the removal of organic matter and nitrogen compounds from ...
Effect of oil concentration and residence time on the biodegradation of α-pinene vapours in two-liquid phase suspended-growth bioreactors
(Elsevier, 2012-02-20)
Recently, research on the use of binary aqueous–organic liquid phase systems for the treatment of polluted air has significantly increased. This paper reports the removal of α-pinene from a waste air stream in a continuous ...
Bioprocesses for air pollution control
(Wiley-Blackwell, 2009)
Bioprocesses have been developed as relatively recent alternatives to conventional, non-biological technologies, for waste gas treatment and air pollution control in general. This paper reviews major biodegradation processes ...
Fungal biocatalysts in the biofiltration of VOC-polluted air
(Elsevier, 2004-09-30)
Gas-phase biofilters used for the treatment of waste gases were originally packed with compost or other natural filter beds containing indigenous microorganisms. Over the past decade much effort has been made to develop ...
Biodegradation of BTEX in a fungal biofilter: Influence of operational parameters, effect of shock-loads and substrate stratification
(Elsevier, 2012-07)
The effect of relative humidity (RH: 30% to >95%) of a gas-phase mixture composed of benzene, toluene, ethylbenzene and para-, meta- and ortho-xylenes (BTEX), inlet concentrations (0.2–12.6 g m−3), and empty bed residence ...
Evaluation of the biomethane potential of solid fish waste
(Elsevier, 2012-07)
Manufacturing processes in fish canning industries generate a considerable amount of solid waste that can be digested anaerobically. The aim of this research was to study the biochemical methane potential of different solid ...
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 ...
