Multiple studies have attempted to link gut microbiota with host lipid metabolism. An important aspect of this is the potential of gut microbiota in supplying long-chain polyunsaturated fatty acids (LC-PUFA) to the host.

This study profiled the changes in gut microbiota composition and function of a mud crab species fed three different diets in terms of LC-PUFA and short-chain PUFA availability, which can potentially be used as substrates to biosynthesis LC-PUFA. In addition, the effect of a diet which also had the short-chain PUFA and inclusion of a general antibiotic was investigated. 

Overall, the findings demonstrated prominence of selected taxonomy groups during limited LC-PUFA intake. Taken together with an increase in various lipid metabolism pathways, the importance of Proteobacteria and the genera Vibrio and Shewanella in supplying LC-PUFA for host was highlighted.
