Bioremediation of sites polluted with petroleum hydrocarbons and heavy metals is a major challenge. The aim of this study was the isolation and characterization of hydrocarbon-degrading and heavy metal-tolerant bacteria. Sixteen hydrocarbonoclastic bacteria were isolated by enrichment from a crude oil-contaminated soil at Aconcagua river mouth, Central Chile. Most strains were cocci-shaped and ...

Nickel-resistant bacteria have been isolated so far only in contaminated soils and wastewaters polluted with different industrial sources. The aim of our study was to determine if nickel-resistant bacteria could also be isolated from human samples. In this brief communication, we describe how we were able to isolate human bacterial strains that grew without oxygen and in the presence of high co...

In this study the ability of Acidithiobacillus ferrooxidans, with regard to the biorecovery of heavy metals inshake flask has been investigated. Adaptation experiments with the single metal ions Ni, Co, V, Mo, W anda mixture of the first four metal ions in the medium was developed through serial sub-culturing. Adaptationshowed that A. ferrooxidans could tolerate up to 2.3 g/l ...

To provide a basis for using indigenous bacteria for bioremediation of heavy metal contaminated soil, the heavy metal resistance and plant growth-promoting activity of 136 isolates from V-Ti magnetite mine tailing soil were systematically analyzed. Among the 13 identified bacterial genera, the most abundant genus was Bacillus (79 isolates) out of which 32 represented B. subtilis and 14 B. pumil...

The present study was designed to evaluate the heavy metal absorbing potential of bacteria isolated from industry effluent sites of river Nagavali, Srikakulam Andhra Pradesh. From the effluent waste water three bacteria were isolated and confirmed as Staphylococcus aureus and Staphylococcus epidermidis and Staphylococcus saprophyticus after performing various biochemical tests. The heavy metal ...

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...

Industrial effluents consist many pollutant and heavy metals. Bacteria isolated from industrial west water ground may have potential to tolerate heavy metal. In this study we isolate a Citrobacter sp. which can resist heavy metal like Cu and Pb. Slurry from industrial west water ground was collected from 22.0663 N, 88.1041 E. The heavy metal content and other parameters of soil were estimated. ...

Pollution of the biosphere by heavy metals has caught our attention in finding new ways to sustain, restore and manage the environment. In this context, the study was carried out to assess and determine the cumulative effect of heavy metals on soil microorganisms and seed germination, which ultimately contribute serious threats to the ecosystem. We attempted to isolate stress tolerant bacteria ...
