Assessment of microbial population size. (A) Microbial community composition from cell pellets using metaproteomics was estimated by total protein count for each community passaged in defined media MOPS + glucose (MOPS) or complex (R2A) media. There was a total of 15 passages per medium and 3 biological replicates per passage. Individual colors in the stacked bar charts represent each microbial member. (B) Cellular estimates of organism relative abundance plotted against extracellular estimates of organism abundance for each passage for MOPS (black circles) and R2A (red circles). Each circle represents the averaged abundance across replicates for a single passage. Proteome depth (number of proteins identified) is plotted for each microbe per sample measured in the defined microbial community passaged across (C) defined MOPS + glucose (black) and (D) complex R2A (red) media
