title: 16S rRNA gene amplicon reads of fractions from stable isotope labeling experiment in soil
design: Soil samples were rewetted with 18O-H2O or 16O-H2O to measure 18O incorporation into DNA for stable isotope probing and growth measurements. DNA from Soil samples  was ultracentrifuged in a CsCl gradient to fractionate and pooled fractions were submitted for 16S rRNA gene amplicon sequencing (515f and 806r) on Illumina Miseq (2x300bp).
