Establishing and analyzing the Simplified Human Intestinal Microbiota (SIHUMI) as a versatile in vitro gut microbiome model with qPCR-based strain-level tracking
Nature Protocols, Published online: 19 March 2026; doi:10.1038/s41596-026-01336-yThis protocol enables users to establish a defined, in vitro consortium composed of seven fully sequenced and anaerobically culturable human gut bacteria and follow the growth of individual members via strain-specific qPCR to evaluate community dynamics in response to interventions.

We previously engineered Saccharomyces cerevisiae through CRISPR-Cas9 integration to produce Ply511, a bacteriophage endolysin active against L. monocytogenes, showing the potential of engineered yeast to produce endolysins for biocontrol. In this study, we extended this approach to the probiotic yeast S. boulardii and directly compared the two yeasts as secretion hosts for Ply511. Using a simulated human gastrointestinal environment, we evaluated their ability to retain endolysin activity and reduce L. monocytogenes levels.
