The functional role of fungi in the gut, a branched story!

The human gut acts as a host to vast populations of microorganisms such as bacteria, viruses, archaea, and fungi. All these microorganisms together residing in the human gut are called the Human Gut Microbiome (HGM). Years of attention and research have already elucidated that the health of the HGM is tightly correlated with the overall health of the individual. Especially the commensal bacteria have shown to influence the food metabolism, nutrient uptake, energy homeostasis, epithelial barrier integrity, host immunological response, and the protection against colonization of pathogens.

The functional role of other key microorganisms in the HGM has, however, not been studied in as much detail, if at all. Fungi are often overlooked yet repeatedly found in observational studies. In this research, we aim to elucidate the functional role that some of the most common yeasts have in the HGM and how it affects the other microorganisms by using a synthetic consortium of HGM bacteria. Furthermore, to investigate the effect of these yeasts when combined with the synthetic consortium on the host, a novel gut on a chip model is used.
