K-region epoxides of benz[a] anthracene, dibenz[a,h] anthracene, and 3-methylcholanthrene have been found to be toxic and more active in producing malignant transformation of cells derived from mouse prostate than their respective parent hydrocarbons and K-region dihydrodiols and phenols. The data support the view that metabolism of these polycyclic hydrocarbons is a prerequisite for their biol...

Mycobacterium sp. strain LB501T utilizes anthracene as a sole carbon and energy source. We analyzed cultures of the wild-type strain and of UV-generated mutants impaired in anthracene utilization for metabolites to determine the anthracene degradation pathway. Identification of metabolites by comparison with authentic standards and transient accumulation of o-phthalic acid by the wild-type stra...

Introduction: Bioremediation convertssoils pollutants to safe and non-toxic substance through metabolic activities of microorganisms. This research was conducted to evaluate the effect of bacteria on removal of phenanthrene and anthracene from polluted soils using chicken manure as an auxiliary substrate. Materials and Methods: First, uniformly-graded soils were transferred to the pilots, then...

Polycyclic aromatic hydrocarbons (such as, anthracene, benzo[a]pyrene and so on) are non-polar, hydrophobic compounds, which are not ionized. They are only slightly soluble in water. They are very dangerous compounds in the environment. The single-walled carbon nanotube (SWNT) is used for removal and conversion of anthracene to low-risk products. In this study, electron transfer between anthrac...

DNA was isolated from mouse embryo cell cultures that had been treated with 7-methylben/[fl]anthracene-3H and subsequently degraded with enzymes to deoxyribonucleosides that were chromatographed on a Sephadex LH-20 column. The resultant hydrocarbon-deoxyribonucleoside products were not present in similar enzyme digests of DNA that had been reacted in aqueous solution with either 7-bromomethylbe...

Anthracene fibers are grown inside a microstructured quartz matrix to form a multicore optical fiber for X-ray detection. A modified fiber growth method for single crystal anthracene from the melt via the Bridgman-Stockbarger technique is presented. The anthracene fiber is characterized by using spectrophotometry, Raman spectroscopy, and X-ray diffraction. These results show the anthracene grow...

polycyclic aromatic hydrocarbons (pahs) such as anthracene, naphthalene, and phenanthren are the most toxic and carcinogenic pollutants which cause severe damages on soil and water resources. in order to remove these materials, biological methods and using potential of local microorganisms of oil contaminated soils are preferred because of cheapness and availability. existing soil microorganism...

A common impurity of 7,12-dimethylbenz[alpha]anthracene was more effective than 7,12-dimethylbenz[alpha]anthracene in inducing morphological alterations, and in causing an increase in glucose uptake, DNA synthesis and cell number in chick-embryo fibroblasts. Gradual morphological transformation follows the increase in DNA synthesis after 2 days when either primary or secondary cultures are trea...
