isolation, identification and optimization of phenanthrene degrading bacteria from the coastal sediments of nayband bay
materials and methods phe degrading bacteria were isolated from surface sediments. isolated strains were then identified by biochemical and molecular (16s rdna gene sequence) analysis. rsm was employed to evaluate the optimum biodegradation of phe by the most effective isolated strain. the investigated parameters included the temperature, inoculum sizes, ph, nh4cl concentration, and salinity. o...
متن کاملIsolation and Identification of Phenanthrene-degrading Bacteria and Increasing the Biodegrading Ability by Synergistic Relationship
Background: Polycyclic aromatic hydrocarbons are a large group of oil contaminants with carcinogenic, mutagenic and teratogenic effects. The release of these compounds in soil destroys animals, plants and microbial diversity and has several negative impacts on physical properties of the soil including the destruction of soil aggregates reduction in pores, and increase in soil bulk density....
متن کاملPhenanthrene degradation in soils co-inoculated with phenanthrene-degrading and biosurfactant-producing bacteria.
Contaminant sorption within the soil matrix frequently limits biodegradation. However, contaminant bioavailability can be species-specific. This study investigated bioavailability of phenanthrene (PHE) to two PHE-degrading bacteria (Pseudomonas strain R and isolate P5-2) in the presence of rhamnolipid biosurfactant and/or a biosurfactant-producing bacterium, Pseudomonas aeruginosa ATCC 9027. Ps...
متن کاملTemporal Variation in Rocky Intertidal Gastropods of the Qeshm Island in the Persian Gulf
Gastropod assemblages were investigated along intertidal rocky shore in the Qeshm Island in the northern Persian Gulf. Monthly sampling was undertaken from May 2007 to April 2008. Environmental factors were also measured in each site. A total of 28 gastropod taxa belonging to 15 families were identified and Cerithiidae was the most abundant family and Cerithium caeruleum was the most abundant...
متن کاملNovel Phenanthrene-Degrading Bacteria Identified by DNA-Stable Isotope Probing
Microorganisms responsible for the degradation of phenanthrene in a clean forest soil sample were identified by DNA-based stable isotope probing (SIP). The soil was artificially amended with either 12C- or 13C-labeled phenanthrene, and soil DNA was extracted on days 3, 6 and 9. Terminal restriction fragment length polymorphism (TRFLP) results revealed that the fragments of 219- and 241-bp in Ha...
