Screening and Separation of Microorganisms Degrading PCBs.
We performed an assay to assess the polychlorinated biphenyl (PCB) degradative capability and congener specificity of aerobic microorganisms. Microbial strains were isolated and separated from different types of soils in the Czech Republic, and their PCB-degrading abilities were compared. An industrial mixture of PCB congeners ranging from dichloro- to hexachlorobiphenyl and representing variou...
متن کاملA small-scale method for screening of lignin-degrading microorganisms.
A new method to facilitate rapid screening of lignin-degrading microorganisms was developed. Fungal strains are cultivated in tissue culture plates containing C-ring-labeled dehydrogenation polymerizate (DHP) (synthetic lignin). Evolved CO(2) is trapped in barium-saturated filter paper and is detected by exposing the paper to X-ray film. Analysis of the autoradiograms, carried out by density me...
متن کاملEnumeration of petroleum-degrading microorganisms.
A variety of factors, including concentration of oil, antibiotics, dyes, and inoculum washes, were examined to determine their effect on the total counts of microorganisms on oil-containing media. The media found to be best for enumerating petroleum-degrading microorganisms contained 0.5% (vol/vol) oil and 0.003% phenol red, with Fungizone added for isolating bacteria and streptomycin and tetra...
متن کاملEnrichment and isolation of endosulfan-degrading microorganisms.
Endosulfan (6,7,8,9,10,10-hexachloro-1,5,5a,6,9,9a-hexahydro-6,9-methano-2,3,4-benzo-dioxathiepin-3-oxide) is a cyclodiene organochlorine currently used as an insecticide all over the world and its residues are posing a serious environmental threat. This study reports the isolation and identification of enriched microorganisms, capable of degrading endosulfan. Enrichment was achieved by using t...
متن کاملThe Comparison of Silica Gel-Alumina Sorbents for Separation of PAHs and PCBs
The aim of this research is to develop a silica gel and alumina column chromatography for separation of polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) into two groups. This is achieved by optimizing the cut-off volume of eluting solvent and weight ratio of silica gel and alumina. In this process mixture of PAHs and PCBs divide in two groups and simultaneously o...
