Heavy metal pollution by natural factors is a world-wide phenomenon. Release of large quantities of heavy metals without handling proper processes that could decrease the concentration of such a material is a hassle that makes strains resistant to these heavy metals apart from entering into human food chain. In this research, wastewater of four firms in Guilan province such as Foolad, Risandegi...

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...

 Heavy metal tolerant bacterial species were isolated from the textile effluents collected Faisalabad, Pakistan. Thirty samples subjected to heavy analysis. Nickel and Cobalt selected for further study on basis of their predominant concentration in all samples. Thirteen screened out as positive Ni bacteria 03 them had typical characteristics which tolerated up 08 mM. These identified AMIC...

Effects of different heavy metals on Vibrio harveyi, V. fischeri, Photobacterium phosphoreum and P. leiognathi were examined. Checkerboard assay was used for the detection of the natural metal tolerance levels of a large number of marine luminous eubacteria. 57 strains of luminous bacteria were investigated for their natural patterns of heavy metal tolerance. The behaviors of these strains were...

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...

The aim of this study was to determine the activity and structure microbial communities in soils contaminated with heavy metals (HMs). To achieve goal, soil samples were taken from two sites (i.e., Piekary Śląskie Bukowno) Poland. A wide range methods applied, including: total metal-tolerant culturable bacteria enumeration; community analysis using phospholipid fatty acid method (PLFA); denatur...
