Cellular organelle evolved repeatedly
NWO researchers have discovered that in the course of evolution hydrogenosomes repeatedly evolved from mitochondria. Hydrogenosomes, or 'hydrogen-forming organelles', are cell organelles that produce hydrogen and energy. They serve as an alternative energy supply in organisms that live without... view more (2001-07-26)

Natural gas inhabited by unusual specialists
A German-American research team of biologists and geochemists has discovered hitherto unknown anaerobic bacteria in marine sediments which need only propane or butane for growth.   view more (2007-09-24)

Paired microbes eliminate methane using sulfur pathway
Anaerobic microbes in the Earth's oceans consume 90 percent of the methane produced by methane hydrates - methane trapped in ice - preventing large amounts of methane from reaching the atmosphere.   view more (2008-01-17)

Remote expertise for wastewater treatment
Getting expertise where it is needed in wastewater treatment is the goal of TELEMAC, which has developed remote, and local monitoring and control solutions so industries can obtain all the benefits of anaerobic waste treatment while minimising costs and complications.   view more (2004-09-27)

Two bacteria better than one in cellulose-fed fuel cell
No currently known bacteria that allow termites and cows to digest cellulose, can power a microbial fuel cell and those bacteria that can produce electrical current cannot eat cellulose.   view more (2007-07-30)

Biogas production is all in the mixing
Engineers at Washington University in St. Louis, using an impressive array of imaging and tracking technologies, have determined the importance of mixing in anaerobic digesters for bioenergy production and animal and farm waste treatment.   view more (2008-04-17)

Deep sea methane scavengers captured
Scientists of the Helmholtz Centre for Environmental Research (UFZ) in Leipzig and the California Institute of Technology (Caltech) in Pasadena succeeded in capturing syntrophic (means "feeding together") microorganisms that are known to dramatically reduce the oceanic emission of methane... view more (2008-05-14)

Breath test can discriminate between a bacterial overgrowth and IBS
The gastrointestinal (GI) tract is colonized by bacteria immediately after birth; Escherichia coli, Streptococci and Clostridi are the first bacteria harboured by the colon, followed by anaerobic Enterococci, Lattobacilli and Bacteroidi.   view more (2007-12-19)

Why exercising muscles tire when needed most
The cause of muscle fatigue during intense exercise is linked directly to the muscle's reliance on anaerobic metabolism for force production, according to a new study by researchers at Rice and Harvard universities.   view more (2006-11-09)

Using microbes to fuel the US hydrogen economy
The focus on hydrogen as a future fuel source is compelling given dwindling supplies of oil and natural gas, as well as escalating costs and the fact that burning fossil fuels releases large amounts of carbon dioxide, a "greenhouse" gas, into the atmosphere.   view more (2006-09-13)

Bacterium could treat PCBs without the need for dredging
Researchers at Rensselaer Polytechnic Institute have discovered a tiny bacterium that could one day transform the way we remove polychlorinated biphenyls (PCBs) from our environment. The organism could be the key to developing methods that help detoxify commercial PCB compounds on site —... view more (2007-03-08)

OU Researchers Isolate Microorganisms That Convert Hydrocarbons to Natural Gas
When a group of University of Oklahoma researchers began studying the environmental fate of spilt petroleum, a problem that has plagued the energy industry for decades, they did not expect to eventually isolate a community of microorganisms capable of converting hydrocarbons into natural gas.   view more (2008-08-20)

Microbial Fuel Cells: Optimization Of The Anode Compartment For Improved Electron Transfer
A microbial fuel cell mimics a biological system, in which bacteria do not directly transfer the energy-rich electrons gained out of the feeding to their characteristic electron acceptor. Instead, the electrons are diverted towards an electrode (anode) and subsequently conducted over a resistance... view more (2003-11-14)

Did you know? The oldest organisms live in waste repositories
Some of the oldest organisms - Archaea - live in waste repositories. These microorganisms have lived on Earth for 3.8 billion years and some of them can produce methane, used as a renewable energy source. Cemagref scientists are trying to enhance their activities so that they produce methane more... view more (2003-06-11)

Renewable energy from farm waste

Life under extreme contidions, microbiology of the hydrothermal vents
Microorganisms are found everywhere, even under the most extreme environmental conditions. These include extremely high temperature environments in which growth of certain Archaea - the most primitive forms of life - is possible at temperatures up to 110oC or higher, and hypersaline environments... view more (2003-05-29)

Two novel species of bacteria isolated from oil wells
Oilfields usually represent extreme environments, where physicochemical conditions appear at first sight to be generally unsuitable for living organisms to develop. However, these environments, usually poor in nitrates and oxygen, harbour a rich diverse community of microorganisms. The most widely... view more (2004-11-23)

Methane gyrations last 2,000 years show human influnece on atmosphere
Humans have been tinkering with greenhouse gas levels in Earth's atmosphere for at least 2,000 years and probably longer, according to a surprising new study of methane trapped in Antarctic ice cores conducted by an international research team.   view more (2005-09-09)

Learning to live with oxygen on early Earth
Washington, D.C. Scientists at the Carnegie Institution and Penn State University have discovered evidence showing that microbes adapted to living with oxygen 2.72 billion years ago, at least 300 million years before the rise of oxygen in the atmosphere.   view more (2006-10-17)

Potential candidate chemical for antidepressant effects of exercise found
The antidepressant effects of exercise may be down to a chemical called phenylethylamine, reports a pilot study in the British Journal of Sports Medicine. Although research suggests that exercise is an effective antidepressant, exactly how it works has not been clear. The study focused on 20... view more (2001-09-26)

REDUCTION OF RICEFIELD METHANE EMISSION
Methane (CH4) is considered to be the third most important gas, after carbon dioxide (CO2) and freons, in its contribution to the greenhouse effect and hence to global warming. Cores taken from the ice cap have shown that its concentration in the atmosphere has tripled in 100 years. This figure... view more (1999-07-07)

Making gas out of crude oil
An international team that includes University of Calgary scientists has shown how crude oil in oil deposits around the world - including in Alberta's oil sands - are naturally broken down by microbes in the reservoir.   view more (2007-12-13)

BSE Residues: anaerobic digestion saves 45 million euros a year
The treatment of BSE residues through anaerobic digestion is, according to Quercus, the most efficient and fruitful way of resolving this environmental question. This is a biological process successfully put into practice in a national company, ITS Marques, and consists of the degradation of... view more (2002-10-18)

Lactic acid not athlete's poison, but an energy source-if you know how to use it
In the lore of marathoners and extreme athletes, lactic acid is poison, a waste product that builds up in the muscles and leads to muscle fatigue, reduced performance and pain.   view more (2006-04-20)

The beat goes on: a vertebrate heart that beats without oxygen
Scientists have discovered that the heart of a carp keeps beating when it is starved of oxygen for five days. "This is the first time that a vertebrate heart has been shown to survive such prolonged periods without oxygen and actually keep beating at the same rate as when oxygen is... view more (2004-04-02)
