Background Clostridium thermocellum is a Gram-positive, anaerobic, thermophilic plant cell wall degrading bacterium capable of converting cellulosic substrates into ethanol. Degradation of cellulose occurs extracellularly in a large complex called the cellulosome. This nanomachine contains about 20 catalytic components, and can attach to the surface of the host organism. The complex is built on a "scaffoldin" subunit onto which the catalytic subunits are added through interactions of the "cohesion" domains of the enzymes with the "dockerin" domains on the scaffold. The C.thermocellum cellulosome is the best-characterized cellulase complex and thus serves as a paradigm. Continuing research on the cellulosome and its producer will provide crucial information for better understanding the cellulolytic reaction, a key process in biomass conversion (adapted from http://genome.jgi-psf.org/cloth/cloth.home.html).Strain LQ8 was isolated by Viljoen 1926.
