Exobiology Research Highlights

Geysers, mud pots, steam vents and hot springs in the region at present known as Yellowstone National Park awed American Indians and early European explorers. Now, both million tourists visit the super C in northwestern Wyoming each year to watch wildlife and billet the spectacular scenery. Scientists home in on the hot springs, exploring their environmental science and plumbing their scalding waters in search of highly adapted, heretofore-undiscovered microorganisms.
gray whale Spring and Mushroom Spring in Yellowstone are two of the most thoroughly studied hot springs on the planet, tell Don Bryant, Ernest C. Pollard professor of biotechnology at Penn State. as yet in these two unwelcoming habitats Bryant and David protect, a microbial ecologist at tonne State University, found a revolutionary thermophilic, or heat-loving, bacterium that survives by transforming light into chemical energy. Bryant, who has studied bacterial photosynthesis in an academic career spanning more than three decades, characterizes finding this new chlorophyl-producing microbe as the discovery of a lifetime.
Bryant and Ward describe the new bacterium, Chloracidobacterium thermophilum (Cab. thermophilum, for short) in a paper published in the July 27, 2007, issue of Science. Not only has the microbe been declared a new genus and species, it is the first phototrophic member of the phylum Acidobacteria. Phyla are major taxonomical groupings of organisms, and there are about 50 phyla of bacteria. Before Bryant and Ward discovered Cab. thermophilum, only five of those phyla included chlorophyll-producing members. Now, Cab. thermophilum has placed the acidobacteria among the ranks of the chlorophyll producers. (In terms of biomass, chlorophyll-producing bacteria are tremendously abundant, and they are essential to our planets ability to sustain life, performing an...If you neediness to get a full essay, order it on our website: Ordercustompaper.com
