FIGURE 1.

Comparison of new (A1–A6) and old workflow (B1–B8) for metaproteomics sample preparation and analysis. In addition, methods for quality control are shown (X1–X3). The time shown represents the shortest possible time in which a single sample can be processed. Under reasonable circumstances five samples can be done in less than 24 h (or 15 samples within 48 h) using the new workflow limited by the number of available mass spectrometer. Similarly, at least 3 days are required for multiple samples using the old workflow.
