MOESM2 of Effects of H2:CO2 ratio and H2 supply fluctuation on methane content and microbial community composition during in-situ biological biogas upgrading

Additional file 2. ASV Catalogue. Multipage PDF format file with 100 facets corresponding to the top 100 most abundant ASVs. The ASV number and associated taxonomy are indicated by the text at the top of each facet. Datapoints in each figure indicate the abundance of the ASV in a reactor replicate sample at the time in days since reactor start-up. The solid line indicates the mean of control reactor abundances and the dashed line indicates that for the hydrogen-supplemented reactors, while symbol shape and fill indicate whether the datapoint corresponds to a reactor without H2 addition (control) or with (H2 supplemented), as indicated in the legend above each plot. Some ASVs indicate zero abundance across all timepoints, presumably because the elimination of samples with less than 1000 sequences resulted in the removal of spurious ASVs that comprised nearly the entirety of the few sequences present in the sample
