Biodegradation of Polychlorinated Biphenyls by and Isolated from Contaminated Soil
Polychlorinated biphenyls (PCBs) cause many significant ecological problems because of their low degradability, high harmfulness, and solid bioaccumulation.Two bacterial strains were isolated from soil that had been polluted with electrical transformer liquid for more than 40 years. The isolates were distinguished as Lysinibacillus macrolides DSM54Tand Bacillus firmus NBRC1530...

nical mixtures found in the formulation and the measurements made on the basis of calibration with these mixtures. Chlorobiphenyl (CB) refers to the individual congener named by the Ballschmiter number. TEQs refer to the sum of the concentration of the congener equivalent to 2, 3, 7, 8 TCDD obtained by using the toxic equivalence factor for each PCB. POLYCHLORINATED BIPHENYLS: GAS CHROMATOGRAPHY
متن کاملRapid enantiomeric separation of polychlorinated biphenyls by electrokinetic chromatography using mixtures of neutral and charged cyclodextrin derivatives.
Electrokinetic chromatography with cyclodextrin derivatives (CD-EKC) was used to achieve the rapid enantiomeric separation of chiral polychlorinated biphenyls (PCBs). Thirteen of the 19 chiral PCBs stable at room temperature were individually separated into their two enantiomers by using 2-morpholinoethanesulfonic acid (MES) buffer (pH 6.5) containing carboxymethylated gamma-cyclodextrin (CM-ga...
متن کاملassessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Biodegradation of polychlorinated biphenyls by rhizobia: a novel finding.
Metabolism of simple aromatic compounds in rhizobial strains has been a subject of study for a few decades, due either to the significance of nutritional diversity in the inoculum survival during agricultural applications or to the importance of plant phenolics in the microbe-plant cross-talk and signal-transduction. Here, we report the capability of rhizobial strains to catabolize polychlorina...
