Fussy microbe holds promise for environmental cleanup
...oxic substance that can then be easily degraded by aerobic
microbes in soil. The beauty of the newly discovered bacterium is that it does its work under water, preventing the toxin from escaping into the atmosphere and causing ozone depletion. Finding TCA1 and understanding how to make it thrive is a first s...

...owing them to dominate the earth. The evolution of aerobic
photosynthesis in bacteria is also the most likely reason for the development of an oxygen-rich atmosphere that transformed the chemistry of the Earth billions of years ago, further triggering the evolution of complex life. After decades of research...

Natural approach to cleaning up toxic freeway runoff urged
...the gravel lets in air that promotes the growth of aerobic
bacteria, creating an effective, natural treatment system. Heavy metals are absorbed by the soil, where they remain trapped. The soil need not be replaced for at least 20 -- and possibly as long as 50 -- years, Stenstrom said. Similar bioinfiltration...
Bacteria convert food processing waste to hydrogen

treatment processes. "Using this continuous fermentation process, we can strip nearly all of the energy out of the wastewater in forms that people can use now. While this approach has high capital costs at the outset, our calculations show that it c...
Few microbiological differences in households using antibacterials
...er colleagues performed a "snapshot" survey of the aerobic
bacteria from bathroom and kitchen surfaces of 38 households located in the greater Boston and Cincinnati areas. They evaluated the total numbers of gram-negative and gram-positive bacteria, including potential pathogens, as well as the frequency of...
Microbe from depths takes life to hottest known limit
...lizes the microbe's description--uses iron the way aerobic
animals use oxygen. "It's a novel form of respiration," Lovley says, explaining how Strain 121 uses iron to accept electrons. (Many archaea also use sulfur). As oxygen does in humans, the iron allows the microbe to burn its food for energy. Chemic...
Study seeks genetic keys to exercise success
...three-day-a-week class that involves 30 minutes of aerobic
exercise each period along with one mini-presentation on aspects of fitness and exercise each week. Completion of the 30-week study requires enrollment in the class in the spring semester as well. Any volunteer is free to withdraw from the researc...
Experimental cancer drugs may halt events that lead to cardiac hypertrophy and heart failure
... healthy physiological response to events, such as aerobic
exercise, where heart cells grow larger like any other well-conditioned muscle. Pathological hypertrophy, however, may result from genetic mutation or, most commonly, from the consequences of an unhealthy cardiovascular system. "The exertion of pus...
