Spirochaeta thermophila

Spirochaeta thermophila is a fairly recently discovered free-living, anaerobic, spirochaete that seems to be the most thermophilic of the Spirochaetales order. The type species was discovered in 1992 in Kuril islands, Russia and described in Aksenova, et al. It has been isolated in the sediments and water columns of brackish aquatic habitats of various ponds, lakes, rivers, and oceans. This organism is identified as a new species based on its unique ability to degrade cellulose, xylan, and other α- and β-linked sugars and use them as the sole carbon source by encoding many glycoside hydrolases. It is presumed to secrete cellulases to break down plant-matter around it but there has been little work on the characterization of the enzymes responsible for this. rdf:langString
