Fungi from geothermal soils in Yellowstone National Park.
Geothermal soils near Amphitheater Springs in Yellowstone National Park were characterized by high temperatures (up to 70 degrees C), high heavy metal content, low pH values (down to pH 2.7), sparse vegetation, and limited organic carbon. From these soils we cultured 16 fungal species. Two of these species were thermophilic, and six were thermotolerant. We cultured only three of these species f...
متن کاملArsenite-oxidizing Hydrogenobaculum strain isolated from an acid-sulfate-chloride geothermal spring in Yellowstone National Park.
An arsenite-oxidizing Hydrogenobaculum strain was isolated from a geothermal spring in Yellowstone National Park, Wyo., that was previously shown to contain microbial populations engaged in arsenite oxidation. The isolate was sensitive to both arsenite and arsenate and behaved as an obligate chemolithoautotroph that used H(2) as its sole energy source and had an optimum temperature of 55 to 60 ...
متن کاملMicrobiology in Yellowstone National Park.
Yellowstone National Park plays host to numerous microbiological research projects — officially 23, according to the 1996 Investigators' Annual Reports. However, once categories such as aquatic ecology, the study of brucellosis and other wildlife diseases, environmental education, geochemistry and geothermal systems, and vegetation are included, the total came to at least 35 in 1996. Research p...
متن کاملAquificales in Yellowstone National Park
Aquificales are metabolically versatile chemolithoautotrophic thermophilic bacteria. This group is widespread in both deep-sea and terrestrial hydrothermal systems. In Yellowstone National Park, they were first described in early descriptions of the biology of the park, and later captured the attention of many microbiologists including Brock, Stahl, Pace, and others. There are four genera curre...
متن کاملBiological nitrogen fixation in acidic high-temperature geothermal springs in Yellowstone National Park, Wyoming.
The near ubiquitous distribution of nifH genes in sediments sampled from 14 high-temperature (48.0-89.0°C) and acidic (pH 1.90-5.02) geothermal springs in Yellowstone National Park suggested a role for the biological reduction of dinitrogen (N(2)) to ammonia (NH(3)) (e.g. nitrogen fixation or diazotrophy) in these environments. nifH genes from these environments formed three unique phylotypes t...
