in this study, it was aimed to determine the effects of ship dismantling zones on distribution ofheavy metal resistance and level of antibiotic resistance of bacterial isolates from eastern aegean sea coast.thirteen isolates were identified by phylogenetic analysis using 16s rdna sequences which indicated that theisolates belonged to genus bacillus. these strains were investigated in respect of...

Co-contamination of antibiotics and heavy metals prevails in the environment, and may play an important role in disseminating bacterial antibiotic resistance, but the selective effects of heavy metals on bacterial antibiotic resistance is largely unclear. To investigate this, the effects of heavy metals on antibiotic resistance were studied in a genome-sequenced bacterium, LSJC7. The results sh...

Two hundred and one strains of Staphylococcus aureus isolated from in-patients and out-patients were examined for sensitivity to antibiotics, heavy-metal ions and ethidium bromide and for phage-typing pattern. Heavy-metal ion resistance was less frequent than reported in previous studies and was as frequent in penicillinase non-producing as producing strains. 'Methicillin-resistant' strains wer...

Halomonas zincidurans strain B6(T) was isolated from a deep-sea heavy metal rich sediment from the South Atlantic Mid-Ocean Ridge. The strain showed significant resistance to heavy metals, especially to zinc. Here we describe the genome sequence and annotation, as well as the features, of the organism. The genome contains 3,325 protein-coding genes (2,848 with predicted functions), 61 tRNA gene...

in recent years, environmental pollution by coal mining is a long-established human activity affecting all levels of life with various environmental impacts by generating heavy metals. the presence of heavy metals even in trace amount is toxic and detrimental to all living organisms. the coal mine area in bokaro is one of the “toxic hotspot” in india. bacteria have evolved uptake and efflux mec...

The use of antibiotic agents as growth promoters was banned in animal husbandry to prevent the selection and spread of antibiotic resistance. However, in addition to antibiotic agents, heavy metals used in animal farming and aquaculture might promote the spread of antibiotic resistance via co-selection. To investigate which heavy metals are likely to co-select for antibiotic resistance in soil ...

agricultural and specifically industrial activities have led to a substantial release of toxic heavy metals in the environment which can constitute a major hazard for ecosystem and human health. biosorption of heavy metals is one of the most effective technologies involved in the removal of toxic metals from contamination sites that has used in the last decade. population and microbial activity...

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...
