BIODEGRADATION AND DECHLORINATION OF PENTACHLOROPHENOL WITH A PENTACHLOROPHENOL DEGRADING BACTERIUM Sphingomonas Chlorophenolica
Pentachlorophenol (PCP) has long been used as a wood preservative. Because of the adverse environmental effects of PCP, it has widely contaminated soil and groundwater. In treating PCP, a number of bacteria have been isolated from the environment and applied to bioremediate contaminated areas. However, there is some controversy about the efficiency of PCP removal. This controversy originates in...
متن کاملIsolation and physiological characterization of the pentachlorophenol degrading bacterium Sphingomonas chlorophenolica.
Many chlorophenols tend to persist in the environment, and they may become public health hazards. Among chlorophenols, pentachlorophenol (PCP) is a priority pollutant that has been used widely as a general biocide in commercial wood treatment. Owing to the rapid industrial growth, serious soil and water pollutions by chlorophenols has been reported in Taiwan. In this study, 10 indigenous PCP-de...
متن کاملStarvation-survival of a p-nitrophenol-degrading bacterium.
An environmental actinomycetes, capable of utilizing p-nitrophenol as its sole carbon and nitrogen source, was starved for an 8-week period and showed no reduction in its ability to biodegrade p-nitrophenol. Microscopic examination revealed that starvation of the bacterium resulted in the fragmentation of filaments into individual cells.
متن کاملPlasmid-mediated mineralization of carbofuran by Sphingomonas sp. strain CF06.
A bacterial strain (CF06) that mineralized both the carbonyl group and the aromatic ring of the insecticide carbofuran and that is capable of using carbofuran as a sole source of carbon and nitrogen was isolated from a soil in Washington state. Phospholipid fatty acid and 16S rRNA sequencing analysis indicate that CF06 is a Sphingomonas sp. CF06 contains five plasmids, at least some of which ar...
متن کاملSensitivity to and Degradation of Pentachlorophenol by Phanerochaete spp.
This research measured mycelial extension rates of selected strains of Phanerochaete chrysorhiza, Phanerochaete laevis, Phanerochaete sanguinea, Phanerochaete filamentosa, Phanerochaete sordida, Inonotus circinatus, and Phanerochaete chrysosporium and the ability of these organisms to tolerate and degrade the wood preservative pentachlorophenol (PCP) in an aqueous medium and in soil. Most of th...
