Emulsifying activity in thermophilic and extremely thermophilic microorganisms

Journal of Industrial Microbiology, 1996
Thermophilic and extremely thermophilic enrichments from several different environments produced cell-associated emulsifiers as did several pure cultures ofArchaea. The bioemulsifiers were effective over a wide range of pH, at NaCl concentrations up to 200 g L−1, and at temperatures up to 80°C.

High Tolerance of Hydrogenothermus marinus to Sodium Perchlorate

Frontiers in Microbiology, 2017
On Mars, significant amounts (0.4–0.6%) of perchlorate ions were detected in dry soil by the Phoenix Wet Chemistry Laboratory and later confirmed with the Mars Science Laboratory. Therefore, the ability of Hydrogenothermus marinus, a desiccation tolerant

Screening and taxonomic characterization of D-amino acid aminotransferase-producing thermophiles

, 1999
To acquire an industrially useful biocatalyst for the enzymatic synthesis and production of various D-amino acids, 1,300 thermophiles isolated from the soil of Korea were analyzed for D-amino acid aminotransferase (DAAT) activity. The enzyme activity was

Data_Sheet_1_Distribution and diversity of anaerobic thermophiles and putative anaerobic nickel-dependent carbon monoxide-oxidizing thermophiles in mesothermal soils and sediments.zip

, 2023
Even though thermophiles are best known from geothermal and other heated systems, numerous studies have demonstrated that they occur ubiquitously in mesothermal and permanently cold soils and sediments.

Screening and characterization of thermostable enzyme-producing bacteria from selected hot springs of Ethiopia

Microbiology Spectrum
Hot springs are potential sources of diverse arrays of microbes and their thermostable hydrolytic enzymes. Water and sediment samples were collected from three hot springs of Ethiopia and enriched on nutrient and thermus agar media to isolate pure ...

The role and relevance of soil thermophiles

, 2018
Thermophiles are present in soils. Although the soil upper layers frequently reach high temperatures above all at medium and low latitudes, high latitudes are also surprising by the presence of thermophiles.
