Identification of biomass-specific proteins. Changes in protein ratios in the exoproteome are shown as volcano plots for each type of biomass versus cellobiose (A). Extracellular proteins were present in different amounts and were identified as being secreted in the presence of a specific type of biomass. These showed an FDR-adjusted P-value of < 0.05 and a fold change in protein ratio of > 2 compared to cellobiose; these are indicated here as blue dots. Thus, four bagasse-, 11 corn germ-, and six rice straw-specific proteins were identified, and they are shown in the Venn diagram (B).
