Phylogenetic trees and growth on lignocellulosic conversion residue. Phylogenetic trees of select Streptomyces (A) and yeast species (B) show the diversity within the tested strains. The bar graphs depict growth of these microorganisms in LCR as the average dry cell weight (mg/mL) of at least 2 mLs of culture from at least two biological replicates with the average dry cell weight (mg/mL) of the microbial consortium at the bottom of each panel. Streptomyces strains capable of moderate (≥ 5 mg/mL DCW) and high (≥ 10 mg/mL DCW) growth after seven days at 28 °C with shaking formed distinct phylogenetic groupings indicated as clade 1 (blue), 2 (red), and 3 (yellow) above. Similarly, the highest growing yeast species after four days rolling at room temperature were from two distinct clades: the Dipodascaceae/Trichomonascaceae clade containing the Blastobotrys or the CUG-Ser1 clade containing the Debaryomyces. The number (n) of species in condensed yeast clades is indicated, and the reported values are the mean and standard deviation of values for all species in that clade. Full growth data are available in Additional file 2: Table S2. Clade, species, and strain designations are available in Additional file 5: Table S7
