Archaea were profiled by targeting the v6 region of the 16S ssu rRNA gene
Bacteria were profiled by targeting the v6 region of the 16S ssu rRNA gene
Eukaryota were profiled by targeting the v9 region of the 18S ssu rRNA gene

The personnel involved in the project:
Duplicate samples were collected at depths of 6 m (bacterial and primary production maximum) and 9 m (chemocline; chlorophyll-a maximum) in lake Fryxell (2 November 2007 and 25 March 2008) and 13 m (chemocline; bacterial production, chlorophyll-a, primary production maximum) and 18 m (hypersaline, bottom of trophogenic zone) in lake Bonney (west Lobe; 30 November 2007 and 12 March 2008). Samples for DNA extraction were filtered onto 0.2-μM Sterivex filters (Millipore, Billerica, MA, USA) and stored with 2.0 ml of Puregene lysis buffer at −20 °C until further processing.
|Study Extent||Sampling occurred during the Austral summer and autumn in lake Fryxell and lake Bonney, Antarctica|
Method step description:
- DNA extraction protocols can be found at http://amarallab.mbl.edu.
- The V6 hypervariable regions of Archaa and bacteria were amplified, while for Eukaryota, amplification of the V9 hypervariable region followed established protocols (Amaral-Zettler et al., 2009). We multiplex-sequenced the resulting amplicons using bar-coded primers (Huber et al., 2007; Amaral-Zettler et al., 2009) on a 454 Genome Sequencer FLX (Roche, Switzerland) using the manufacturer’s recommended protocol.
