    The effect of Lactobacillus pentosus strain S-PT84 (S-PT84) on postprandial hypertriacylglycerolemia was investigated in rats. S-PT84 dose-dependently inhibited the hydrolysis of triacylglycerols by pancreatic lipase in vitro. Intragastric administration of S-PT84 significantly reduced the lymphatic recovery of 3H-trioleoylglycerol up to 8 h. The oral administration of a fat emulsion, with or without S-PT84, resulted in the concentration of plasma triacylglycerol 2 h and 3 h after administration being significantly lower in the S-PT84 group than in the group without S-PT84 (control group). These results suggest that S-PT84 alleviated postprandial hypertriacylglycerolemia by delaying triacylglycerol absorption in the intestine through the inhibition of pancreatic lipase.
