Figure 3.
Non-metric multi-dimensional spacing (NMDS; A,C,E) analysis of (A) archaeal, (C) bacterial and (E) SRB DGGE profiles; and unweighted pair-group methods using arithmetic averages (UPGMA) dendrograms (B,D,F), with associated banding patterns, illustrating temporal analysis of (B) archaeal, (D) bacterial and (F) SRB populations. Excised bands from DDGE gels (as described in Table 3) are indicated by arrows.
