Description and significance

Halobacterium sp. NRC-1 is an exceptionally halophilic archaeon that has given us much insight on elemental cellular processes common to all life forms because of its extreme lifestyle. Because Halobacterium sp. NRC-1 can be easily cultured and is genetically well-behaved, studies of genetic, transcriptomic, proteomic and bioinformatics as well as archaea in general have been helpful during its research in laboratories. Its genome sequence has also been completed in the year of 2000 helping to give research on DNA replication and repair systems, phototrophic, anaerobic, as well as lateral gene transfer over time.

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?

Bacillus Licheniformis is a Gram positive, thermophillic bacterium. Its optimal growth temperature is 50°C, but it can also survive at much higher temperatures. Its optimal temperature for
