Methods & Sampling

The microbes isolated during this work were originally enriched from Catalina Harbor sediments from electrodes poised at reducing or electron donating redox potentials. Isolates are obtained from these enrichements based on the oxidation of elemental sulfur, elemental iron, or amorphous FeS. Approximately 30 isolates from 8 phylotypes were obtained. Ribosomal 16S sequences were obtained for all isolates using direct 16S rRNA amplification from pure culture DNA extracts. The universal bacterial primers 27F (5'-AGAGTTTGAT CCTGGCTCAG) and 1492R (5'-GGTTACCTTGTTACGACTT) were used. Approximately 20–40 ng of PCR product from each isolate were purified with a DNA Clean Concentrator Kit (ZymoResearch, Irvine, CA), and Sanger sequencing was per- formed viaGenewiz (La Jolla,CA) or BeckmanCoulter Genomics (Danvers, MA).

Data Processing Description

These nearly full length sequences were quality checked and assembled using Geneious 7.1© (Biomatters, New Zealand). Alignment of sequences against the Silva database was performed using the SINA aligner (v 1.2.11) (Pruesse et al., 2012; Quast et al., 2013). Nearest cultured representative microbes were also obtained through the Silva database (Quast et al., 2013). Maximum-likelihood estimation trees were constructed from alignments of sequences and nearest neighbors using RaxML (v.8) (Stamatakis, 2014) to assign taxonomy. A identity of 97% was used to designate a specific genera for a given sequence. All full length sequences have been deposited to Genbank (accession numbers KM088025-KM0 88033).

BCO-DMO Processing:
- separated location into lat and lon columns;
- converted degrees and decimal minutes to decimal degrees;
- replaced commas with semi-colons;
- replaces spaces with underscores;
- modified parameter names to conform with BCO-DMO naming conventions.
