Mycobacterium parascrofulaceum in acidic hot springs in Yellowstone National Park.
Mycobacterium parascrofulaceum was found in Norris Geyser Basin, Yellowstone National Park, in a system composed of two acidic (pH 3.0) springs with temperatures between 56 degrees C at the source and 40 degrees C at the confluence of both springs. Growth and survival assays at 56 degrees C for 60 days were performed, confirming the origin of the strain.
متن کاملDepositional facies and aqueous-solid geochemistry of travertine-depositing hot springs (Angel Terrace, Mammoth Hot Springs, Yellowstone National Park, U.S.A.).
Petrographic and geochemical analyses of travertine-depositing hot springs at Angel Terrace, Mammoth Hot Springs, Yellowstone National Park, have been used to define five depositional facies along the spring drainage system. Spring waters are expelled in the vent facies at 71 to 73 degrees C and precipitate mounded travertine composed of aragonite needle botryoids. The apron and channel facies ...
متن کاملCharacterization of some thermophilic bacteria from the Hot Springs of Yellowstone National Park.
Extensive enzymatic studies have been conducted on cell-free fractions from a thermophilic bacterium designated as National Canners Association strain 2184 and tentativelv identified as Bacillus stearothermophilus Donk (1920), (Militzer et al., 1949, 1950, 1951, 1952; Georgi et al., 1951; h'Iarsh and Militzer, 1952). Preparatory to extending these investigations to other thermophilic bacteria, ...
متن کاملDepositional Facies and Aqueous–solid Geochemistry of Travertine-depositing Hot Springs (angel Terrace, Mammoth Hot Springs, Yellowstone National Park, U.s.a.)— Discussion
Terrestrial CaCO3 precipitates, including travertines, tufas, and speleothems, are currently of great interest because of their potential as archives of environmental, climatic, and biologic information (e.g., Andrews et al. 1997; Bar-Matthews et al. 1997; Walter and Des Marais 1993). Detailed studies of examples of these terrestrial carbonates therefore provide valuable information to aid inte...
متن کاملArchaeal and bacterial communities in three alkaline hot springs in Heart Lake Geyser Basin, Yellowstone National Park
The Heart Lake Geyser Basin (HLGB) is remotely located at the base of Mount Sheridan in southern Yellowstone National Park (YNP), Wyoming, USA and is situated along Witch Creek and the northwestern shore of Heart Lake. Likely because of its location, little is known about the microbial community structure of springs in the HLGB. Bacterial and archaeal populations were monitored via small subuni...
