Metaproteomics is the large-scale characterisation of the entire protein complement of a microbiota directly from an environment at a given point in time. Research examining environmental and human-associated microbiomes via multi-omics is expending rapidly. Especially, functional meta-omic approaches such as metaproteomics are currently employed intensively and provide a more comprehensive picture of multiple environments and their associated microbial communities than what could be done previously. The International Metaproteomics Symposium is the leading event in the field of metaproteomics and related…
