Fig. 3From: Key sub-community dynamics of medium-chain carboxylate productionSpearman’s rank order correlation was applied to test for links between the relative cell abundance values of all 31 sub-communities and caproate (C6) and caprylate (C8) concentrations. The correlation approach comprised the three periods: (2a) the initial caproate and caprylate increase from day 6 to day 45 , (2b) the second caproate increase from day 57 to day 111 and (2c) the second caprylate increase from day 132 to day 185 were analysed. Correlation strength (rS), significance (p) and corrected significance (pBH) are provided in Additional file 1: Table 1 S11. Sub-communities chosen for sorting are marked in bold and additionally provided in Additional file 1: Table 3 S11. The strong correlations (rS > | ± 0.7|) these sub-communities were chosen for are marked with a white dotBack to article page
