Taxonomic composition of eight sub-communities sorted at different time points due to their strong correlations with the target carboxylates (Fig. 3). Every sub-community composition is given with its relative cell abundance ● and the sub-communities mean relative cell abundance . The detailed relative cell abundance development is given in Additional file 1: S12. The relative OTU and cell abundances are assigned to time points with the respective caproate ■ and caprylate ▲ concentrations and eight experimental stages (see Fig. 1). The taxonomic composition is resolved to the genus level applying an abundance threshold of 0.1%. OTUs with abundances below 1% are summarised to “Others”. Details about library preparation, sequencing and sequence data analysis are given in Additional file 1: S13
