Biodegradação bacteriana de compostos organoclorados

open access: yesQuímica Nova, 2014
Due to their recalcitrant nature, organochlorides are already found in environment and the search for alternatives to eliminate these compounds such as biodegradation using native microorganisms is of great interest.

Environmental Impact of Flame Retardants (Persistence and Biodegradability) [PDF]

open access: yesInternational Journal of Environmental Research and Public Health, 2009
Flame-retardants (FR) are a group of anthropogenic environmental contaminants used at relatively high concentrations in many applications. Currently, the largest market group of FRs is the brominated flame retardants (BFRs). Many of the BFRs are considered toxic, persistent and bioaccumulative.

Kelvin Probe Force Microscopy in Bionanotechnology: Current Advances and Future Perspectives

open access: yesAdvanced Materials, EarlyView.
Kelvin probe force microscopy (KPFM) enables the nanoscale mapping of electrostatic surface potentials. While widely applied in materials science, its use in biological systems remains emerging. This review presents recent advances in KPFM applied to biological samples and provides a critical perspective on current limitations and future directions for

Simulation of benzene transport and biodegradation during transient hydraulic conditions [PDF]

open access: yes, 2000
Thesis (M.S.) University of Alaska Fairbanks, 2000MODFLOW and BIOMOC were used to simulate transport and biodegradation of benzene in the alluvial aquifer adjacent to the Chena River. MODFLOW was used to calculate ground water fluxes at the boundaries of

Analytical modelling of stable isotope fractionation of volatile organic compounds in the unsaturated zone [PDF]

open access: yes, 2011
Analytical models were developed that simulate stable isotope ratios of volatile organic compounds (VOCs) near a point source contamination in the unsaturated zone. The models describe diffusive transport of VOCs, biodegradation and source ageing.

Biodegradation of plastics in soil and effects on nitrification activity. A laboratory approach.

open access: yesFrontiers in Microbiology, 2014
The progressive application of new biodegradable plastics in agriculture calls for improved testing approaches to assure their environmental safety. Full biodegradation (≥ 90%) prevents accumulation in soil, which is the first tier of testing.

Pyrolysis of asphaltenes and biomarkers for the fingerprinting of the _Amoco Cadiz_ oil spill after 23 years [PDF]

open access: yes, 2009
The chemical composition of the petroleum products accidently or deliberately released in the environment varies considerably with time under the action of biological (biodegradation) and physico-chemical (photo-oxidation) processes.

Molecular characterization of mesophilic and thermophilic sulfate reducing microbial communities in expanded granular sludge bed (EGSB) reactors [PDF]

open access: yes, 2008
The microbial communities established in mesophilic and thermophilic expanded granular sludge bed reactors operated with sulfate as the electron acceptor were analyzed using 16S rRNA targeted molecular methods, including denaturing gradient gel ...
