  The “Strategies for Rationally Designing and Assembling Synthetic Microbial Consortia” section (page unavailable) says proteomics and metabolomics can help predict interactions, while high-throughput screening makes interaction analysis more efficient. But the “Combined Top-down and Bottom-up Strategy” section describes interactions as still unpredictable and difficult to manage.
