Table 1 Pairwise statistical comparison of similarity (ANOSIM, 10,000 permutations) for samples from the bacterial and the archaeal sample groups respectively for a given reactor (fermenter or post digester) and the indicated two time phases

From: Process parameters and changes in the microbial community patterns during the first 240 days of an agricultural energy crop digester
