Cold water coral microbiomes: Paramuricea placomus

Compared to tropical corals, much less is known about deep-sea coral biology and ecology. Although the microbial communities of some deep-sea corals have been described, this is the first study to characterize the bacterial community associated with a deep-sea octocoral, Paramuricea placomus. Samples from five colonies of P. placomus were collected from Baltimore Canyon (379–382 m depth) in the Atlantic Ocean off the east coast of the United States of America. DNA was extracted from the coral samples and pyrosequenced using Roche 454 with titanium chemistry and V4-V5 primers targeting the 16S rRNA genes of the coral-associated bacterial community.
