The Biodegradation of Certain Components of Town Waste by Thermophilic Fungi
… This suggested that those cellulolytic thermophiles which chad been isolated from composting town waste were successful in colonising this substrate because they were able to adapt to environmental parameters _imposed by such a system, This was partially confirmed by a study of the …

Diversity and activity of aerobic thermophilic carbon monoxide-oxidizing bacteria on Kilauea Volcano, Hawaii
… CO oxidation. Culture-based methods targeting thermophiles at these sites yielded 31 newly isolated thermophilic CO-oxidizing strains in 8 genera. Two strains were formally described as novel species. The isolation of multiple Thermogemmatispora strains (Class: Ktedonobacteria) led to …

Expansion of Deltaproteobacteria diversity from marine sediment reveals unique metabolic features
… several dsr genes are related to those from thermophiles. This study expands the genetic catalog of Deltaproteobacteria and provides a better ecological context for Deltaproteobacteria worldwide. The description of these new lineages highlights that there is much to be learned about this …

REPSA Directed Assessment of Native Cleavage Resistance of DNA to Type IIS Restriction Endonucleases and Modification of REPSA for High Temperature Application
… for the discovery of new DNA-binding proteins in thermophiles (HT-REPSA). We utilized <em>Thermus thermophilus </em>(HB-8/ATCC 27634/DSM 579) as a test organism due to its amenable nature in a laboratory setting and current status as a model thermophilic organism. We used a TetR Family (TFR) …
