Gut metabolome meets microbiome: A methodological perspective to understand the relationship between host and microbe

Publication date: Available online 30 April 2018 Source:Methods Author(s): Santosh Lamichhane, Partho Sen, Alex M. Dickens, Matej Orešič, Hanne Christine Bertram It is well established that gut microbes and their metabolic products regulate host metabolism. The interactions between the host and its gut microbiota are highly dynamic and complex. In this review we present and discuss the metabolomic strategies to study the gut microbial ecosystem. We highlight the metabolic profiling approaches to study faecal samples aimed at deciphering the metabolic product derived from gut microbiota. We also discuss how metabolomics data can be integrated with metagenomics data derived from gut microbiota and how such approaches may lead to better understanding of the microbial functions. Finally, the emerging approaches of genome-scale metabolic modelling to study microbial co-metabolism and host–microbe interactions are highlighted.
