Figure 1.
Percentage contribution of 16S rRNA gene sequences (grouped by class) during acetate enrichment under mesophilic (M) or thermophilic (T) temperature conditions, as determined using Illumina MiSeq sequencing. Chemostats designated MH/TH and ML/TL received medium containing 7.5 and 0.4 g acetate l−1 respectively. The corresponding hydraulic retention time (HRT) at the point of sampling is given on the x‐axis. Yellow, green, blue and red bars represent classes within the phyla Bacteriodetes, Firmicutes, Proteobacteria and Thermotogae respectively. Purple indicates methanogenic archaea. Classes representing < 1% were included in minor classes.
