جدا سازی باکتری های تجزیه کننده هیدروکربن های آروماتیک چند حلقه ای (PAH) از دریاچه مهارلو و بررسی اثر غلظت نمک در تجزیه آن ها
Background and Aim: In this research we isolated the bacterial species degrading polycyclic aromatic hydrocarbons (PAHs) and determined optimal salt concentration for PAH degradation.Materials and Methods: We used naphthalene and anthracene as the only sources of carbon for isolating PAH-degrading bacteria the main culture medium was ONR7a. The bacteria isolated by this method were used for the...

Polycyclic Aromatic Hydrocarbons (PAHs) are among of potentially hazardous chemicals for environment and cause health concern. These compounds exhibit carcinogenic and/or mutagenic properties and are listed by the United States Environmental Protection Agency (USEPA) as priority pollutants. Polycyclic Aromatic Hydrocarbons are hardly degraded and therefore bioremediation is often considered as...
متن کاملIsolation and Identification of Pyrene-degrading Bacteria from Soils around Landfills in Shiraz and Their Growth Kinetic Assay
Background & Objectives: Pyrene is a kind of carcinogen hydrocarbon in environment and one of the top 129 pollutants as ranked by the U.S.Environmental Pretection Agency (USEPA). Today's commodious method that is considered by many researchers is the use of microorganisms to degrade these compounds from the environment. The goal of this research is separation and identification of the indigenou...
متن کاملDifferential detection of key enzymes of polyaromatic-hydrocarbon-degrading bacteria using PCR and gene probes.
Bacteria with ability to degrade polyaromatic hydrocarbons (PAHs), isolated from wastewater and soil samples, were investigated for their taxonomic, physiological and genetic diversity. Eighteen isolates able to metabolize naphthalene or phenanthrene as sole carbon source were taxonomically affiliated to different subclasses of the Proteobacteria (Sphingomonas spp., Acidovorax spp., Comamonas s...
متن کاملIsolation of marine polycyclic aromatic hydrocarbon (PAH)-degrading Cycloclasticus strains from the Gulf of Mexico and comparison of their PAH degradation ability with that of puget sound Cycloclasticus strains.
Phenanthrene- and naphthalene-degrading bacteria were isolated from four offshore and nearshore locations in the Gulf of Mexico by using a modified most-probable-number technique. The concentrations of these bacteria ranged from 10(2) to 10(6) cells per ml of wet surficial sediment in mildly contaminated and noncontaminated sediments. A total of 23 strains of polycyclic aromatic hydrocarbon (PA...
