Rubrobacter radiotolerans strain RSPS-4 is a slightly thermophilic member of the phylum "Actinobacteria" isolated from a hot spring in São Pedro do Sul, Portugal. This aerobic and halotolerant bacterium is also extremely resistant to gamma and UV radiation, which are the main reasons for the interest in sequencing its genome. Here, we present the complete genome sequence of strain RSPS-4 as wel...

Twenty-five patients with intractable asthma had swimming training in a hot spring pool for 3 months. The subjects were divided into three groups according to their clinical symptoms and ages. Changes of ventilatory function during swimming training were observed in in each group. The ventilatory function test revealed that free swimming training in a hot spring pool for 30 min did not induce b...

The Mars rover Spirit encountered outcrops and regolith composed of opaline silica (amorphous SiO2·nH2O) in an ancient volcanic hydrothermal setting in Gusev crater. An origin via either fumarole-related acid-sulfate leaching or precipitation from hot spring fluids was suggested previously. However, the potential significance of the characteristic nodular and mm-scale digitate opaline silica st...

Measurement of natural radionuclides concentration in Samosir area of Sumatera island of Indonesia aims to obtain basis data of the content of radionuclides that could be tended in the development of the area. This research was conducted using Neutron Activation Analysis (NAA), which consists of a sampling of soil of Samosir Island as the residential area and the soil surrounding of Pangururan ...

Phytases (myo-inositol hexakisphosphate phosphohydrolases; EC 3.1.3.8) catalyze the hydrolysis of phytic acid (myoinositol hexakisphosphate) to the mono-, di-, tri-, tetra-, and pentaphosphates of myo-inositol and inorganic phosphate. Therrmophilic bacteria isolated from water sampled from hot spring. About 120 isolates of bacteria were successfully isolated form hot spring water sample and tes...
