Identification of Bacteroides acidifaciens as an Arabinoxylan-Responsive Gut Bacterium Using D-Amino Acid Metabolic Probe Technology

Key Points

• The aim is to identify the gut bacterium Bacteroides acidifaciens and its response to arabinoxylan.
• Utilized D-amino acid metabolic probe technology to monitor gut bacteria responses.
• Measured short-chain fatty acid (SCFA) production and evaluated intestinal barrier function.
• Arabinoxylan significantly increased SCFA production by Bacteroides acidifaciens.
• Enhanced intestinal barrier function was noted, indicating positive health impacts.
