  1. Eight human faecal samples, the corresponding culture without yeast mannan (CUL), and the corresponding culture with the 0.4% yeast mannan preparation (YM) were sampled 30 h after the initiation of fermentation. Values are the mean ± standard deviation. Asterisks (*) represent significant differences (*p < 0.05) (n = 8) between microbiota in the original faeces and the microbiota in corresponding cultures without or with yeast mannan using the Kruskal–Wallis test.
