SIP soil, Monkey_Run forest, treated with 13C-Van, sampled on day 30, replicate 2, fraction 28
DNA-SIP fractions samples fractionated from CsCl gradient while unfractionated, bulk, and enrichments were just DNA extracts, PCR with V4 16S rRNA primers, gel cleanup, then up to 192 samples sequenced together with dual barcodes in Illumina MiSeq 2x250 V2 chemistry.
