Heavy Metal Tolerance of Sediment Bacteria Isolated from Coastal City (izmir,turkey)
نویسندگان
چکیده
In this study, it was aimed to determine of heavy metal resistance of bacterial isolates from coastal city sediment (Izmir Bay). Thirty isolates (Bacillus, Marinibacillus, Halobacillus) were identified by phylogenetic analysis and these strains were investigated in respect of the MICs of heavy metals (Hg, Cu, Cd, Cr, Ni and Pb). The MICs of heavy metals were different for each strain but the general order of resistance to the metals was found to be as Ni>Pb>Cu>Cr>Cd>Hg. It can be concluded that bacterial isolates were sensitive to Hg but were highly resistant to Ni (13mM) and Pb (6mM). Additionally, the highest concentrations of metals were found in the inner part of the bay, where intensely industrialized compared to the middle and outer parts of the bay.

Detection of Plasmids in Heavy Metal Resistance Bacteria Isolated from the Persian Gulf and Enclosed Industrial Areas
Several heavy metal resistant bacterial strains were isolated from sediment and water samples collected from the Persian Gulf and enclosed industrial areas. All the isolated bacteria were identified by 16S rRNA gene sequencing. Isolated bacteria were tested for the presence of plasmids using the modified alkaline lysate method. The method was effective for identification and characterization of...

Urban rivers having different catchment areas and properties are investigated in order to infer their heavy metal contribution to the Izmir Inner Bay. The concentrations of Cd, Cr, Cu, Ni, Pb, and Zn in the waters and sediments of these rivers were measured and compared with the limit values given in the Sediment Quality Guidelines and Screening Quick Reference Tables (SQuiRTs). Metal concentra...
