In most developing parts of the world, the rapid expansion of industrial areas leading to uncontrolled processing and utilization of industrial products, agricultural inputs, vehicular emissions and improper disposal of liquid and solid wastes may cause soil to become contaminated with chemical hazards such as heavy metals. Heavy metal contamination of soil may pose risks to humans and the ecos...

Abstract Continuous occurrence of heavy metals is a major cause environmental pollution due to its toxic effects. At minimum concentrations, these are highly reactive and can gather in the food chains web, causing dangers public health concerns. Soil samples were collected from Paharang drain, Faisalabad. Cadmium tolerant bacteria isolated evaluated for their MIC against Cd. The bacterial strai...

A gene coding for a de novo peptide sequence containing a metal binding motif was chemically synthesized and expressed in Escherichia coli as a fusion with the maltose binding protein. Bacterial cells expressing the metal binding peptide fusion demonstrated enhanced binding of Cd2+ and Hg2+ compared to bacterial cells lacking the metal binding peptide. The potential use of genetically engineere...

Co-contamination of the environment with toxic chlorinated organic and heavy metal pollutants is one of the major problems facing industrialized nations today. Heavy metals may inhibit biodegradation of chlorinated organics by interacting with enzymes directly involved in biodegradation or those involved in general metabolism. Predictions of metal toxicity effects on organic pollutant biodegrad...

heavy metal pollution all around the world has become a major environmental concern and the bioremediation of polluted environments is an increasingly popular strategy due to both its efficiency and safety. in this study, a bacterial strain resistant to heavy metal was isolated from metal contaminated sites. strain mkh2 was removed pb (ii) with 95.06%. this isolate was also resistant to zinc, c...

This study was conducted with the aim of applying Bioremediation technology in order to identify efficiency some bacterial isolates for improving quality wastewater discharging from a tank Al-Hindiyah district sewage water treatment station Karbala Governorate. The included use bacteria remove heavy metals (Cd), as 120 were isolated before entering and after leaving under study, it appeared tha...

the species of pseudomonas genus show different levels of resistance to soil's heavy metals pollution. since, there exists is a relationship between heavy metal resistance and plasmid profile of bacteria, in this study, plasmid profile of plant growth promoting rhizobacteria (pgpr) pseudomonas fluorescence isolates were studied in the presence of cadmium and zinc. the bacteria were initial...
