Bacterial 16S community from biofilms formed on a limestone settling plate in the Atlantic Ocean, at a depth of approximately 1340 meters.
DNA was extracted using a Qiagen DNeasy extraction kit, and was sequenced on a 454 pyrosequencing platform using GS FLX Titanium chemistry using primers 563F/926R to target the V4V5 region of the 16S rRNA gene. Barcode: ACATACGCGT
