TL;DR: Special emphasis is laid on EPS controlling strategies which would have the great potential in promoting microbial aggregates performance and in alleviating membrane fouling, including limitation strategies and elevation strategies which have been confirmed to be feasible and promising to enhance system performance.
Metaproteomics: Studying functional gene expression in microbial ecosystems
Paul Wilmes,Philip L. Bond +1 more
TL;DR: The recent availability of extensive metagenomic sequences from various environmental microbial communities has extended the postgenomic era to the field of environmental microbiology as mentioned in this paper, however, the application of proteomic investigations to complex microbial assemblages such as seawater and soil still presents considerable challenges.
