New Routes for Aerobic Biodegradation of Dimethylsulfoniopropionate [PDF]

open access: yesApplied and Environmental Microbiology, 1991
Dimethylsulfoniopropionate (DMSP), an osmolyte in marine plants, is biodegraded by cleavage of dimethyl sulfide (DMS) or by demethylation to 3-methiolpropionate (MMPA) and 3-mercaptopropionate (MPA). Sequential demethylation has been observed only with anoxic slurries of coastal sediments.

Carbon isotope fractionation during aerobic biodegradation of trichloroethene by Burkholderia cepacia G4: a tool to map degradation mechanisms [PDF]

open access: yes, 2002
The strain Burkholderia cepacia G4 aerobically mineralized trichloroethene (TCE) to CO2 over a time period of similar to20 h. Three biodegradation experiments were conducted with different bacterial optical densities at 540 nm (OD(540)s) in order to test

Stable carbon isotope fractionation in chlorinated ethene degradation by bacteria expressing three toluene oxygenases

open access: yesFrontiers in Microbiology, 2012
One difficulty in using bioremediation at a contaminated site is demonstrating that biodegradation is actually occurring in situ. The stable isotope composition of contaminants may help with this, since they can serve as an indicator of biological ...

Effects of thermochemical pretreatment on the biodegradability of sludge from a biological wastewater treatment system [PDF]

open access: yesMaejo International Journal of Science and Technology, 2010
The effects of thermochemical pretreatment on the sludge biodegradability were examined. Two types of tests were conducted: aerobic biodegradation and denitrification using thermochemically pretreated sludge as carbon source.

Improvement of Bioremediation Performance for the Degradation of Petroleum Hydrocarbons in Contaminated Sediments

open access: yesApplied and Environmental Soil Science, 2011
Microcosm bioremediation strategies were applied to sediments contaminated with hydrocarbons. Experiments were performed in aerobic conditions in a single-step treatment and in a two-step anaerobic-aerobic treatment.

An investigation into the bioremediation of black olive brine wastewater [PDF]

open access: yes, 2005
In South Africa, the table olive industry is burgeoning and as a consequence, the large volume of fermentation wastewaters that are generated have created environmental concerns, as these wastewaters have the potential to pollute rivers and ground waters.

Biodegradation of phenol by aerobic granulation technology

open access: yesWater Science and Technology, 2009
High organic load and fluctuation in organic load in terms of total phenols is fed into a SBR of higher height and diameter ratio (H/D 20) and operated at 4 h cycle basis with a volumetric exchange ratio of 50% resulting in a constant HRT of 8 h. Successful cultivation of aerobic granules was achieved.
