Helping chlorine-eating bacteria clean up toxic waste

...coccoides ethenogenes, discovered in Ithaca sewage sludge in 1997 by James Gossett, Cornell professor of civil and environmental engineering, and isolated and studied by Stephen Zinder, Cornell professor of microbiology, are now in wide use to detoxify such carcinogenic chemicals as perchloroethylene (PCE) ...

New science of metagenomics 'will transform modern microbiology'

...soil and seawater, or managed environments such as sludge processing sites. The large projects would be "virtual" centers collecting data from scientists working at many locations around the world, and would probably need to be sustained for 10 years, the report notes. They would also serve as incub...

Enzyme shreds Alzheimer's protein

...n the brain snips apart the protein that forms the sludge called amyloid plaque that is one of the hallmarks of Alzheimer's disease (AD), researchers have found. They said their findings in mice suggest that the protein, called Cathepsin B (CatB), is a key part of a protective mechanism that may fail in som...

Better sludge through metagenomics

...lished the first metagenomic study of an activated sludge wastewater treatment process. The research appeare...quence information directly from samples of sewage sludge to provide a blueprint of the genes and hence the metabolic possibilities of the wastewater environm...

'Sticky' mice lead to discovery of new cause of neurodegenerative disease

... a novel mechanism behind the buildup of the toxic sludge that accumulates in neurons. Researchers have long known that neurodegenerative disorders can be caused by the gradual yet persistent accumulation of misfolded proteins in neurons that eventually triggers cell death. But this new mechanism points to ...

Delft water-purification method promises radical improvement

... research subject. With the new aerobic granular sludge technology (Nereda TM), aerobic (thus oxygen using...or practical implementation. The aerobic granular sludge technology is very promising, and has been nominated for the Dutch Process Innovation Award 2006. Th...

Earth Rx: A microbial biotechnology prescription for global environmental health

...hen wastewater was cleaned up by a bacterial-laden sludge that speeds up the breakdown of the organic material in sewage. With recent advances in biology, materials, computing, and engineering, environmental biotechnologists now are able to use microbial communities for a wealth of services to society. T...

UCR environmental scientists propose chemical solution to cleaning California's Salton Sea

...ment to remove phosphorus and solids, and then the sludge is collected and disposed. Alum, or aluminum sulfate, is the most widely used coagulant in water treatment. It forms solid amorphous aluminum hydroxide in water, which incorporates soluble phosphorus into its structure. The amorphous aluminum hydrox...

Chernobyl: The true scale of the accident

..., but led to secondary contamination of sewage and sludge systems. Radiation in air above settled areas returned to background levels, though levels remain higher where soils have remained undisturbed. How contaminated are agricultural areas? Weathering, physical decay, migration of radionuclides down the...
