Microbiological data for Fe microbial mats.
Sequence frequency proportion for the most abundant OTUs in the four vent samples (Politeia spire-1: NA014-03, Champagne active mound: NA014-07, Poet's Candle: NA014-16, microbial mat covering the ocean floor: NA014-42). OTUs are represented by their close relatives (>99% sequence similarity; comparison to GenBank entries using BLAST Basic Local Alignment Search Tool, NCBI, Bethesda, MD, USA). Most OTUs were closely related to clones previously retrieved from Fe-rich mats (e.g. clone FJ497617 in NA014-003 and NA014-016), hydrothermal vents (e.g. clones GQ848456 and JQ287193 in NA014-003, AF181991, JN860339 and JN860355 in NA014-007 and FN553842 in NA014-042), massive sulphide deposits (clones AB722105 in NA014-003 and AB722160 in NA014-007) and hydrothermal sulphides (clone JQ28719 in NA014-003).
