Microbial dehalogenation of polychlorinated biphenyls in aerobic conditions.
From soils contaminated with polychlorinated biphenyls (PCBs) a strain of Alcaligenes sp. able to grow in a mineral medium with a commercial mixture of PCBs as carbon source was isolated. This strain consumed up to 200 ppm in seven days in laboratory conditions. After 24 h of incubation, some new congeners of PCBs could be recognized by mass spectrometry. Through the identification of these com...
متن کاملDehalogenation of trichloroethylene in microbial electrolysis cells with biogenic palladium nanoparticles.
Nanopalladium catalysts can be synthesized by the precipitation of palladium (Pd) on the surface of bacteria leading to the production of biogenic Pd nanoparticles (bio-Pd). For example, Shewanella oneidensis can reduce Pd(II) and subsequently precipitate it as Pd(0) nanocrystals on their cell wall and in their periplasmic space when a hydrogen donor is provided (De Windt et al., 2005). No expe...

متن کاملTechnology of Catalytic Dehalogenation of Pops
The present work deals with the results of the basic and applied research of mechanisms of formation and detoxification of dioxins and chemically similar compounds (“dioxin-like compounds), especially PCDF, PCB, OCP and others. The problem has already been treated by the authors theoretically. This work is concerned with application consequences of the results of laboratory and pilot plant test...
متن کاملComparison of trichloroethylene reductive dehalogenation by microbial communities stimulated on silicon-based organic compounds as slow-release anaerobic substrates.
Microcosm studies were conducted to demonstrate the effectiveness of tetrabutoxysilane (TBOS) as a slow-release anaerobic substrate to promote reductive dehalogenation of trichloroethylene (TCE). The abiotic hydrolysis of TBOS and tetrakis(2-ethylbutoxy)silane (TKEBS), and the biotic transformations of the hydrolysis products from both were also investigated. Comparison of TCE reductive dehalog...
