Overview of the differentially expressed proteins (FDR < 0.1, and fold-change ≥ 2.0) among the lysate samples from glucose or lignin fermentation after 5 days. Relative abundances were log2 transformed. Each row represents one protein and each column represented one sample. “G1” and “G2” are the lysate duplicate samples from glucose fermentation; “L1” and “L2” are the lysate duplicate samples from lignin fermentation. All the fermentation was conducted by co-culture of three strains: R. jostii RHA1, R. jostii RHA1 vanA⁻, R. opacus PD630. The gene names of strains follow the protein names abbreviation: gene names starting with “RHA1” = R. jostii RHA1 or R. jostii RHA1 vanA⁻ while gene name starting with “Pd630” = R. opacus PD630 (Additional file 3). a The selected up-regulated proteins. b The selected down-regulated proteins. A list of abbreviations can be found in Additional file 3
