Aerobic biodegradation of nonylphenol by cold-adapted bacteria
Biotechnology Letters, 2003Three strains capable of mineralizing nonylphenol as sole carbon source were isolated from a sample of contaminated soil and characterized as two Pseudomonas spp. and a Stenotrophomonas sp. The two Pseudomonas spp. expressed characteristics typical of psychrophiles growing optimally of 10 degrees C and capable of growing at 0 degree C.

Strategies for the Aerobic Biodegradation of Dinitrotoluenes
1999Dinitrotoluenes (DNT) are intermediates in the production of the explosive 2,4,6-trinitrotoluene (TNT) and precursors of toluenediisocyanate used in the manufacture of polyurethane foams (Hartter, 1985) Disposal practices associated with TNT manufacturing dating back to World Wars I and II, have resulted in an enormous contamination problem at ...

Aerobic biodegradation of amines in industrial saline wastewaters
Chemosphere, 2011The treatment of hypersaline wastewaters represents a challenge since high salt concentrations disrupt bacteria present in normal biological treatments. This study was conducted to determine the fate of amines in two hypersaline wastewaters obtained from an industrial treatment plant processing influents with 3% and 7% of NaCl.

Biodegradation of polylactide in aerobic and anaerobic thermophilic conditions
Chemosphere, 2002Biodegradable polymers are designed to resist a number of environmental factors during use, but to be biodegradable under disposal conditions. The biodegradation of polylactide (PLLA) was studied at different elevated temperatures in both aerobic and anaerobic, aquatic and solid state conditions. In the aerobic aquatic headspace test the mineralisation

p-Nitrophenol Biodegradation by Aerobic Microbial Granules
Applied Biochemistry and Biotechnology, 2012Mixed microbial consortia in the form of aerobic microbial granules (AMG) capable of xenobiotic degradation can be developed from activated sludge or by adaptation of microbial granules pre-grown on labile carbon sources. Both of these approaches were investigated for the cultivation of AMG capable of p-nitrophenol (PNP) biodegradation.

Aerobic biodegradation of trichloroethene without auxiliary substrates
Water Research, 2014Trichloroethene (TCE) represents a priority pollutant and is among the most frequently detected contaminants in groundwater. The current bioremediation measures have certain drawbacks like e.g. the need for auxiliary substrates. Here, the aerobic biodegradation of TCE as the sole growth substrate is demonstrated.

Comparison of Aerobic and Anaerobic Biodegradation of Sugarcane Vinasse
Applied Biochemistry and Biotechnology, 2015Vinasse is the main liquid waste from ethanol production, and it has a considerable pollution potential. Biological treatment is a promising alternative to reduce its organic load. The aim of this study was to analyze the biodegradation of sugarcane juice vinasse in aerobic and anaerobic conditions.

AEROBIC BIODEGRADATION OF A SILVER-BEARING PHOTOPROCESSING WASTEWATER
Environmental Toxicology and Chemistry, 1998Abstract Aerobic biodegradation of a photoprocessing wastewater (with a silver level attained after silver recovery) was assessed using fill-and-draw activated sludge reactors. The extractability of silver from the resulting waste activated sludge was also determined.

Aerobic biodegradation of propylene glycol by soil bacteria
Biodegradation, 2012Propylene glycol (PG) is a main component of aircraft deicing fluids and its extensive use in Northern airports is a source of soil and groundwater contamination. Bacterial consortia able to grow on PG as sole carbon and energy source were selected from soil samples taken along the runways of Oslo Airport Gardermoen site (Norway).
