Taxonomic abundances and metabolic profiles of the chimney community. A) Comparison of taxonomic abundances based on protein- and DNA-based analyses. Proportions were obtained using selected data shown in Supplementary Tables 1 (16S rRNA gene amplicon sequences), eight (normalized whole genome coverages), 14, and 15 (proteomics). B) Metabolic pathways/genes involved in biogeochemical cycles of C, N, and S found in the genomic and proteomic inventories of 21–64-14-affiliated bacteria. A percentage in parentheses indicates genome completeness.
