Olavius symbionts metagenome

Juvenile and adult specimens of the marine oligochaetes Olavius algarvenis and Olavius ilvae (gutless worm lacking a mouth, gut and nephridia) were collected from silicate sediments in a bay off Capo di Sant' Andrea, Elba, Italy. Four co-occurring bacterial symbionts were identified and shown to be capable of carbon fixation, which provides the host with multiple sources of nutrition. The WGS project and sequences deposited into the Trace Archive can be found using the Project data link.
