Polycyclic aromatic hydrocarbons (PAH) are toxic, mutagenic, and carcinogenic compounds. Removal of these compounds has a great importance for environment. Removal of PAHs from soil is difficult as these chemicals are persistent in the soil. In this research, bioremediation of soil contaminated by (PAH) using Bacillus subtilis DSMZ 3256 (B.subtilis) strains was studied. The effect of electrokin...

Background and Objective: Phenylketonuria (PKU) is a metabolic disorder that is caused by mutations in the phenylalanine hydroxylase (PAH) gene. The multiplicity of mutations in the PAH gene of PKU leads to the cases, in which the pathogenic mutation cannot be detected. In these cases, the variable number of tandem repeat (VNTR), which is the polymorphic marker associated with the PAH gene, is ...

The cultivable fungal diversity from PAH-contaminated sediments was examined for the tolerance to polycyclic aromatic hydrocarbon (PAH). 85 strains, isolated in non-selective media, revealed a large by ribosomal internal transcribed spacer (ITS) sequencing, even including possible new species. Most strains (64%) exhibited PAH-tolerance, indicating that retain diverse PAH-tolerant fungi. PAH-tol...

background : heavy metals and pah s in flue gas have received considerable attention in recent years due to their mutagenic or carcinogenic properties. pah s are products of incomplete combustion of carbonaceous compounds at high temperatures. heavy metals are released into the ambient air from the same sources as those earlier mentioned for pah s . the present study was carried out to investig...
