Value and reason for sequencing

Shewanella woodyi ATCC 51908 was originally isolated from the squid, sediment and water of the Alboran Sea (mixture of Atlantic and Mediterranean Sea) as a bioluminescent bacterium. Like its relative S. sediminis , S. woodyi was also able to degrade RDX with relatively lower activity. Genome sequencing of S. woodyi and S. Sediminis as a pair will help understand how species of Shewanella degraded RDX.

Shewanella are ubiquitous in marine environment and play important role in global carbon and nitrogen cycles. S. woodyi and S. sediminis are two bacteria from different geological regions of marine environment and have many complementary properties in carbon and nitrogen metabolism. Genome sequencing and comparative genomics of multiple strains of Shewanella will be used to unlock the genetic processes involved in carbon, nitrogen cycles and biodegradation of pollutants in marine environment.

It is used in comparative genomics and in the carbon and nitrogen cycle in the marine environment. It's growth is at low temperature.
