Background & Aims: Human beings are constantly exposed to different radiations that have always been recognized as a health hazard. Radon -222 and its daughter products are major sources of natural radiations and a significant total inhalation dose is related to them. Hence, the measurement of radon activity in the environment has gained an increasing importance. In this study, with the measure...
Despite the ubiquity of ammonium in geothermal environments and the thermodynamic favorability of aerobic ammonia oxidation, thermophilic ammonia-oxidizing microorganisms belonging to the crenarchaeota kingdom have only recently been described. In this study, we analyzed microbial mats and surface sediments from 21 hot spring samples (pH 3.4 to 9.0; temperature, 41 to 86 degrees C) from the Uni...
Anoxybacillus suryakundensis strain JS1(T), a facultative anaerobic, moderately thermophilic, alkalitolerant bacterium, was isolated from a hot spring. The estimated genome is 2.6 Mb and encodes 2,668 proteins.
Thermus sp. strain CCB_US3_UF1, a thermophilic bacterium, has been isolated from a hot spring in Malaysia. Here, we present the complete genome sequence of Thermus sp. CCB_US3_UF1.
A Bacillus cereus strain, FT9, isolated from a hot spring in the midwest region of Brazil, had its entire genome sequenced.
Air filter samples collected at Sodankylä (6722’N, 2639’E) were analyzed for determining concentrations of Cs, Sr and total beta in surface air at northern Finland during 1963. Activity concentrations of Cs, Sr and total beta varied seasonally being highest in spring and summer, due to enhanced transportation of aerosols containing radioactive particles from stratosphere to troposphere during w...
The Sulfolobales archaea have been found inhabiting acidic hot springs all over the world. Here, we report the 1.798-Mbp draft genome sequence of the thermoacidophilic Sulfolobales archaeon AZ1, reconstructed from the metagenome of a Mexican hot spring. Sequence-based comparisons revealed that the Sulfolobales archaeon AZ1 represents a novel candidate genus.
