Introduction

Intestinal microbiota form various volatile substances and are thought to be linked to health or disease. Analysis of these volatile substances and exploratory research to discover new biomarkers are also underway. In this article, the gases that evolved from stool samples taken from germ-free (GF) mice and mice colonized with normal microbiota (previously germ-free mice: Ex-GF) were analyzed and a comparative study was conducted. GCMS was used for a comprehensive analysis of the evolved gases, and GC-SCD was used to analyze sulfur-based gases.
