Naphthalene is an ubiquitous pollutant of the environment and the biodegradation of this pollutant has been receiving constant scientific consideration. The aim of this study was to isolate and identify bacteria that could degrade naphthalene from three regions of the Gol Gohar Mine at Sirjan, Iran. In this study, the total naphthalene degrading bacteria were quantified with the most probable n...

in the study of the effects of salicylate on population density of naphthalene degrading bacteria and heterotrophic bacteria in a sample or: soil polluted with aromatic hydrocarbons, two different concentrations of salicylate (16, 160) ?g / gr of soil incubated for 30 days. at 160 ?g / gr, salicylate enhanced the density of naphthalene degraders and heterotrophic bacteria for 30 days. no chenge...

The marine cyanobacterium Oscillatoria sp. strain JCM oxidized naphthalene predominantly to 1-naphthol. Experiments with [1-2H]naphthalene and [2-2H]naphthalene indicated that 1-naphthol was formed with 68 and 74% retention of deuterium, respectively. No significant isotope effect was observed when the organism was incubated with a 1:1 mixture of naphthalene and [2H8]naphthalene. The results in...

Over fifty bacterial strains were isolated from seawater samples in the presence of naphthalene as a sole source of carbon and energy. Among them, three isolates with higher growth rate and naphthalene degradation ability were selected for further studies. Biochemical and molecular analysis revealed that two Persian Gulf isolates, strain PG-10 and strain PG-48 belonged to the group of hydrocarb...

Glutathione plays many critical roles within the cell, including offering protection from reactive chemicals. The bioactivated toxicant naphthalene forms chemically reactive intermediates that can deplete glutathione and covalently bind to cellular proteins. Naphthalene selectively injures the nonciliated epithelial cells of the intrapulmonary airways (i.e., Clara cells). This study attempted t...

To determine the non-bonded interaction energies between Naphthalene and B12N12 Nano ring in different orientations and distances, geometry of molecules with B3LYP method and 6-31g* basis set optimized. Also reactivity and stability of Naphthalene alone and in the presence B12N12 Nano ring checked. Then calculated the NBO, NMR, FREQ, NICS and muliken charge of Naphthalene atoms alone and in the...
