These are presented in the same order as in the dendrogram (Figure 7). Taxa with an average fraction in excess of 1.0% of total Illumina reads are presented in decreasing order. N3, N2, N1 and 0 represent incubations of the indicated oils with 10–80 mM, 10–20 mM, 10 mM nitrate or without nitrate, respectively.
