In recent years, many research groups paying attention in removal of heavy metal ions from polluted areas and also controlled drug delivery applications with the hydrogels based on both biomaterials and synthetic grade. Contamination with these heavy metal ions has also increased public concerns because of their toxicity even at lower concentrations, besides non-biodegradability and tendency of...

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...

bioremediation of heavy metals remains a major challenge in environmental biotechnology. biosorption is a novel technique for decreasing metal ion content in the waste water. biosorption experiments for cu (ii) were investigated in this study using bacteria isolated from the industrial effluent. the results showed that the dead cells of pseudomonas sp. were an efficient adsorbent of cu (ii). fo...

the biosorption of heavy metals can be an effective process for the removal of such metal ions from aqueous solutions. in this study, the adsorption properties of nonliving biomass of phanerochaete chrysosporium for pb (ii) and zn (ii) were investigated by the use of batch adsorption techniques. the effects of initial metal ion concentration, initial ph, biosorbent concentration, stirring speed...

The pollution of the environment with toxic heavy metals is spreading throughout the world along with industrial progress. The present study deals with isolation, identification and characterization of heavy metal tolerant bacteria. Heavy metal tolerating bacteria was isolated from Mula river, Chinchwad, Pune, Maharashtra, India. On the basis of morphological, biochemical, 16S rDNA gene sequenc...

The exponential growth of Industrialization with the increase in human population has led to a heavy metal pollution problem, which has become ubiquitous from air to soil. Heavy metal pollution has become a more serious environmental problem in the last several decades as a result of its toxicity and insusceptibility to the environment. There are many bioremediation technologies including bioso...
