A qualitative approach to nickel and lead uptake by heavy metal resistant bacteria Klebsiella sp. 10KN
Urbanization, industrialization and other human activities has introduced a number of heavy metal contaminants in the environment. Microorganisms inhabiting such sites are well efficient in developing resistance strategies against toxic heavy metal stress. The present work qualitatively describes uptake of nickel (Ni) and lead (Pb) by epiphytic root bacteria isolated from the rhizosphere of the...
متن کاملPlasmid Mediated Tolerance and Removal of Heavy Metals by Enterobacter sp
Problem statement: The role of plasmid in the heavy metal resistance and accumulation by endophytic bacteria was investigated. Approach: The experimental results showed that high level plasmid mediated Cd and Zn resistance in this strain is due to decreased Cd and/or Zn uptake/accumulation by resistance strain. Results: Based on the fact that subsequent plasmid curing experiments demonstrated t...
متن کاملIsolation and molecular characterization of bacteria to heavy metals isolated from soil samples in Bokaro Coal Mines, India
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...

متن کاملuptake and removal capability of toxic heavy metals from the industrial discharge of mobarakeh steel complex by metal accumulating plants
introduction heavy metals are largely found in dispersed form in rock formations. industrialization and urbanization have increased the anthropogenic contribution of heavy metals in the biosphere. heavy metal pollution not only affects the production and the quality of crops, but also influences the quality of the atmosphere and water bodies, and threatens the health and life of human beings. c...
