Topmost expressed bacterial MAGs obtained from sampled FL bacteria. In total, 44 highly expressed bacterial FL MAGs were selected, and a maximum-likelihood tree was computed in anvi’o v7.1 based on protein sequences of 38 universal single-copy genes. Taxonomic affiliations according to GTDB r207_v2 are provided for each MAG with corresponding Silva r138.1 affiliations in parenthesis. Corresponding phyla (class for Proteobacteria) are represented by background colors. Protein expression based on summarized protein abundances as a percentage of bacterial normalized weighted spectra (%BacNWS) are represented by heatmaps: (i) overall expression (shades of green), (ii) expression of SusC-like proteins (shades of purple), and (iii) expression of TonB-dependent transporters (TBDTs) except for SusC-like proteins (shades of blue)
