Metabolic potential of bacterial communities in the fractions based on metagenomic read annotations. Gene counts were normalized according to gene length and the coverage of the single copy rpoB gene. (A) 10 most abundant GHs in each fraction. rpoB-normalized GH counts were additionally transformed into relative abundances with respect to all annotated carbohydrate-active enzymes in each sample. (B) The proportion of the community predicted to encode representative genes for aerobic and anaerobic respiration.
