Genoscope in undertaking the sequencing of the genome of the bacterium Staphylococcus xylosus C2a. The size of the genome of this strain is estimated at about 2.8 Mb. The genome will be sequenced at 12X coverage using three libraries: 15,000 inserts of 3 kb cloned in the pcdna2.1 vector (high copy number), 7,500 inserts of 10 kb cloned in the pCNS vector (low copy number) and about 1,000 inserts of 20-25 kb cloned in a miniBAC vector (pBBC).
