Mapping of the identified metaproteins to the Anaerobic Digestion Model 1. Identified metaproteins were assigned to the single steps of the Anaerobic Digestion Model 1. Significant differences between the assumed steps in the Anaerobic Digestion Model 1 and the proved steps by the identified metaproteins were highlighted in RED or BLUE color. Aspects that were not covered by metaproteomics analysis are displayed in gray (e.g., “Inert compounds”). For each of the analyzed steps a summary provides the most important findings of this study.
