Description and significance
Like most species from the Clostridium genus, Clostridium thermocellum is a bacteria that has a rod-like shape for its cell body. It is classified as a gram-positive bacteria which means that the cell body is only surrounded by a single bilayer lipid membrane. Because it is a gram-positive bacterium, the outside of the cell membrane also contains a thick cell wall known as murein, which is made of peptidoglycans. C. thermocellum is an anaerobic and thermophilic organism that produces spores. In addition, it has celluar structures and mechanism that give it motility in the environment it resides in. The organism was completely isolated and sequenced at the DOE Joint Genome Institute. The bacterium had its genome completely sequenced because it contains a unique extracellular enzyme system capable of breaking down insoluble cellulose into ethanol which is vital for biomass energy. Because of its ability to break down cellulose, it is highly likely that c. thermocellum can be isolated from many plant organisms.
Genome structure
Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence? Does it have any plasmids? Are they important to the organism's lifestyle?
Cell structure and metabolism
Describe any interesting features and/or cell structures; how it gains energy; what important molecules it produces.
Ecology
Describe any interactions with other organisms (included eukaryotes), contributions to the environment, effect on environment, etc.
Pathology
How does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
Application to Biotechnology
Does this organism produce any useful compounds or enzymes? What are they and how are they used?
