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 ...
Mesophilic and thermophilic biotreatment of BTEX-polluted air in reactors
(Wiley-Blackwell, 2007-08)
This study compares the removal of a mixture of benzene, toluene, ethylbenzene, and all three xylene isomers (BTEX) in mesophilic and thermophilic (50°C) bioreactors. In the mesophilic reactor fungi became dominant after ...
A Comparative Study of Physical and Chemical Processes for Removal of Biomass in Biofilters
(MDPI, 2011-08)
After 6 months of operation a long-term biofilter was stopped for two weeks and then it was started up again for a second experimental period of almost 1.3 years, with high toluene loads and submitted to several physical ...
Removal of methanol from air in a low-pH trickling monolith bioreactor
(Elsevier, 2008-09)
A novel ceramic monolith bioreactor colonized by a methanol-degrading culture was investigated in order to assess its suitability for waste gas treatment. The acidotolerant yeast Candida boidinii was identified as dominant ...
Formaldehyde biodegradation and its inhibitory effect on nitrification
(Wiley-Blackwell, 2004-05)
The simultaneous removal of formaldehyde and ammonium in aerobic cultures and the inhibitory effect of formaldehyde on ammonium oxidation were investigated. The influence of a co-substrate, methanol, on formaldehyde ...
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 ...
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 ...
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, ...
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 and effect of formaldehyde and phenol on the denitrification process
(Elsevier, 2005)
Formaldehyde and phenol biodegradation during the denitrification process was studied at lab-scale, first in anoxic batch assays and then in a continuous anoxic reactor. The biodegradation of formaldehyde (260 mg l−1) as ...
