Starch (alfa 1,4 and alfa 1,6 glucan) is processed by gut microbiota (e.g., Bacteroides thetaiotaomicron)
Functional model of glycan processing based on the eight-gene Bacteroides thetaiotaomicron starch utilization system (Sus)). Individual starch processing steps are:
- Step 1: Glycans pass through the superficial capsular polysaccharide layer.
- Step 2: Glycans are bound by components associated with the outer membrane, such as SusD, which makes di…
