A CFU counts of cultured fractions obtained from dilution 10−6 in triplicate for each preservation condition including all individuals (n= 103), significant differences were observed between condition P4 and conditions P1 and P2, respectively (Kruskal–Wallis with post hoc Dunn test, p < 0.001; p < 0.01 for both). B Community variation of cultured fractions and original faecal samples at genus level visualized by principal coordinates analysis (genus level Bray-Curtis distances). Samples were coloured by donor identity and include all preservation conditions and dilutions (n=140, 11 faecal samples and 129 cultured fraction samples). C Variables contributing most to compositional variation in the cultured fractions (dbRDA, genus-level Bray-Curtis distances), either independently (univariate effect sizes in dark blue/grey) or in a multivariate model (cumulative effect sizes in light blue/grey), bars in blue are significant, in grey not significant p<0.001
