The isolation of a new thermophilic bacterium, Thermus aquaticus gen. n. and sp. n., is described. Successful enrichment requires incubation at 70 to 75 C, and the use of nutrient media relatively dilute with respect to the organic components. Strains of T. aquaticus have been isolated from a variety of thermal springs in Yellowstone National Park and from a thermal spring in California. The or...

The thermal conductivity, thermal diffusivity and heat capacity per unit volume of dunite rocks taken from Chillas near Gilgit, Pakistan have been measured simultaneously using transient plane source technique. The temperature dependence of thermal transport properties is studied in the temperature range 83-303 K. Different relations for the estimation of thermal conductivity are also tested. T...

Abstract The hay bacillus Bacillus subtilis has attracted scientific interest for more than 100 years due to its ability form heat-stable spores as an example of a rather simple differentiating organism. Thus, this bacterium became one most studied model organisms. Moreover, B. is used in many biotechnological applications and even food production. Current research still adds novel amazing prop...
