Biotechnologies based on microbial species capable of destroying harmful pollutants are a successful way to solve some the most important problems associated with clean environment. The subject investigation is Antarctic fungal strain Aspergillus glaucus AL1. culturing examined was performed 70 mg wet mycelium being inoculated in Czapek Dox liquid medium containing naphthalene, anthracene, or p...

Polycyclic aromatic hydrocarbons (PAHs) are widespread pollutants and they can cause cancer, abnormality mutation. Nine natural PAHs-degrading bacteria were obtained from polluted areas. These the bacterial mixture degrade phenanthrene, anthracene, pyrene benzo[a]pyrene. The increase degradation rates of several PAHs compounds, such as phenanthrene benzo[a]pyrene, during repaired process, these...

K-region epoxides of dibenz(a,h)anthracene and benz(a)anthracene were more active in producing malignant transforma tion of hamster embryo cells than the corresponding hydrocarbons, K-regions CMand frans-dihydrodiols and phenols. The cytotoxicity exerted by epoxides, relative to the other derivatives, varied among those tested. The 8,9-epoxide (non-K-region) of benz(a)anthracene was less active...

Acidovorax sp. strain NA3 was isolated from polycyclic aromatic hydrocarbon (PAH)-contaminated soil that had been treated in a bioreactor and enriched with phenanthrene. The 16S rRNA gene of the isolate possessed 99.8 to 99.9% similarity to the dominant sequences recovered during a previous stable-isotope probing experiment with [U-(13)C]phenanthrene on the same soil (D. R. Singleton, S. N. Pow...

the major sources of pahs are anthropogenic. these may be generated by pyrolytic and petrogenic processes. low molecular weight pahs come into the aquatic system through the accidentally leakage of oil spills. incomplete combustion at high temperature will release high molecular weight pahs by products of pyrolytic processes. the methods for assigning sources of pahs include paired isomeric rat...

Fifty-two soil samples were collected from various location of the Hisar city. These samples were analysed for six polycyclic aromatic hydrocarbons (naphthalene, acenaphthene, phenanthrene, anthracene, fluoranthene, and pyrene). Total mean concentration of six PAHs varied from 51.79 to 148.82 mg kg(-1) dry weight of the soil, PAH concentration was higher in soil samples from local auto market w...

GRAPHICAL ABSTRACT ABSTRACT Phenanthrene is one of the most recalcitrant components of crude oil-contaminated wastewater. An efficient phenanthrene-degrading bacterium Pseudomonas sp. strain named LZ-Q was isolated from oil-contaminated soil near the sewage outlet of a petrochemical company. Pseudomonas sp. LZ-Q is able to degrade 1000 mg/L phenanthrene in Bushnell-Hass mineral salt medium. ...

Abstract Polycyclic aromatic hydrocarbons (PAHs) are persistent organic pollutants (POPs) that widely distributed in the environment and cause significant environmental damage. Furthermore, they endanger human health by polluting food from natural processing. Therefore, it is necessary to accurately detect PAHs various sample matrices, which requires precise, practical, rapid detection methods....

The products of aqueous chlorination reactions of 1-methylnaphthalene, fluorene, dibenzofuran, anthracene, phenanthrene, 1-methylphenanthrene, fluoranthene, and pyrene have been determined. The conditions employed for these reactions approximated those that might be encountered in water treatment facilities. Reactions at pH greater than 6 tended to produce oxygenated products (epoxides, phenols...
