title: SoTa_1B_UTE
design: Nucleic acids were extracted from two duplicates of 0.22-m Sterivex units. A first PCR step performed to amplify the targeted DNA region (bacterial and archaeal 16S rRNA gene and eucaryotic 18S rRNA gene). Illumina MiSeq adaptors and barcodes were added during the second PCR step (dual indexed with multiple identifiers).
