Maximum-likelihood dendogram of Clostridium with representative members of clusters I–XIX, based on 16S rRNA gene sequences. Sequences from this work were in bold faces (numbers of identical sequences from the same library were shown within the parentheses), with red labels for C24 (35 °C 60-day sample) clone library, blue and green labels for C9 (35 °C 12-day sample) and B21 (25 °C 55-day sample) library, respectively. Clusters and subclusters were indicated by the vertical bars. Eight new clusters and subclusters were named by CLOS (with their corresponding T-RF length within the parentheses). Sequence of Synechococcus PCC6301 was used as outgroup. Bootstrap values (percentage of 1000 replicates) with corresponding significant (>50) were shown on the internal branches obtained from neighbor-joining and maximum parsimony methods or a ‘—’ if not significant (<50). The bar represents 0.1 change per nucleotide pair.
