Action Of Prebiotic Sugar May Spawn New Probiotic Products

August 21, 2009: 08:25 AM EST
A new generation of pre- and probiotic products may be in the offing, now that scientists have discovered that genetically modified bacteria can be activated by a prebiotic sugar. Treating Bacteroides ovatus with a natural tree bark sugar known as xylan stimulates production of proteins that activate the intestinal immune system. That procedure turned out to be an effective treatment for colitis in test animals. “This is the first time that anyone has been able to control a therapeutic protein in a living system using something that can be eaten,” said a lead researcher.
