Microbial Bioremediation of Heavy Metals and Chromium Contamination
This research community focuses on using microorganisms to remove toxic heavy metals, particularly hexavalent chromium, from contaminated soil and industrial wastewater.
The work centers on isolating bacteria, such as Bacillus species, and algae capable of reducing toxic hexavalent chromium to less harmful trivalent forms or binding heavy metals like cadmium, lead, and copper through biosorption. Key methods include electrokinetic remediation, the use of extracellular polymeric substances, and the development of microbial consortia for treating tannery effluents and industrial waste. The research also examines the oxidative stress and toxicity mechanisms these metals induce in biological systems, providing the mechanistic basis for selecting effective remediation agents.
The community is most heavily concentrated in chromium research, accounting for 10.0% of all tracked chromium studies and comprising 10,070 papers. It also represents a significant share of cadmium (0.9%) and lead (0.7%) research, with 1,487 and 1,387 papers respectively.
There are 20,206 papers in this community, primarily published in the Journal of Hazardous Materials, Chemosphere, and Biological Trace Element Research.
Recent work continues to focus on algal-bacterial symbiotic systems for wastewater treatment, the oxidation of chromium in soil systems, and biological approaches to mitigating pollution from battery production effluents.
