Principal Coordinate Analysis (PCoA) clustering of normalized and Hellinger-transformed SIP metagenome sequencing data based on Bray-Curtis distances of a SSU rRNA gene taxonomic classification and b ORF taxonomic classification. No EPS: incubation without WH15EPS. Unlab.: EPS-incubation containing 12C-WH15EPS. Heavy: “heavy fraction” of incubations containing 13C-WH15EPS
