Researchers analyzed 10 strains of Shewanella, a genus important for bioremediation, and found significant genetic differences despite similarities. The study reveals that similarity in gene regulation is a key factor in determining phenotypic similarity among closely related strains.
Researchers from Caltech and JPL found evidence that ancient stromatolites were built with the help of equally ancient microorganisms, providing insight into the earliest record of life on Earth. The discovery may also provide a new avenue for exploration in the search for signs of life on Mars.
A $1 million grant will fund a five-year study using bioremediation to promote bacterial growth in soil subsurface, scrubbing radioactive metal. This method has the potential to clean up an estimated 1.7 trillion gallons of contaminated water and 40 million cubic meters of contaminated soil nationwide.
The DOE JGI has completed its 100th microbial genome sequencing, marking a significant achievement in the field of microbiology. This milestone allows researchers to explore and expand their understanding of microorganisms' metabolic profiles and environmental implications.
Researchers found that bacteria's worst enemy in nuclear waste sites may be toxic metals, contradicting conventional wisdom. Actinides are less toxic than other metals, suggesting bioremediation using naturally occurring bacteria can still be effective.

A NASA scientist has discovered a new species of organism that thrives in a salty, alkaline environment without oxygen. The Spirochaeta americana microorganism can survive in conditions inhospitable to humans and is of great interest to astrobiologists studying the possibility of life on Mars.
Researchers at Georgia Institute of Technology have isolated a novel bacterium, Dehalococcoides strain BAV1, that can degrade toxic chlorinated compounds like PCE and TCE into non-toxic ethene. The discovery holds promise for cleaning contaminated groundwater and subsurface environments, offering a new hope for bioremediation strategies.
Researchers at UC Riverside have isolated microorganisms that can degrade up to 90% of the toxic pesticide endosulfan in 15 days. The strains, Fusarium ventricosum and Pandoraea sp., have potential applications for detoxifying contaminated soils and water bodies.
Researchers have identified two microorganisms, Fusarium and Pandoraea spp., that can degrade the toxicity of endosulfan, a persistent organic pollutant. This breakthrough offers a potential solution for detoxifying contaminated sites, reducing toxic residues in soil.
Researchers are studying the natural processes that clean up acid and heavy metal-contaminated water at a Massachusetts mine site.
