^aBray-Curtis similarity between fresh and preserved planktonic microbiota (plankM) and sessile microbiota (sessM) after 24-h batch fermentations. Data represent means and standard deviations of results from three replicates obtained from fermentation F1 and F2.

^bBray-Curtis similarity of lyophilized microbiota is significantly different from that of cryopreserved microbiota (P < 0.05).

^cBray-Curtis similarity of preserved sessM is significantly different from that of preserved plankM (P < 0.05).
