title: DNA extract from sand column at 11C after 70d incubation
design: "Barcoded amplicon libraries of the small subunit ribosomal RNA gene hypervariable region V5-V7 were generated for each of the individual sample as described previously (Kraneveld et al. 2012), pooled and sequenced by means of the Genome Sequencer FLX Titanium system (Roche, Basel, Switzerland)."
