title: The gastrointestinal transit tolerance of Lactobacillus plantarum strain No. 14 depended on the carbon source.
abstract: This study aimed to assess variations in the human gastrointestinal transit tolerance of Lactobacillus plantarum strain No. 14 after culture with glucose and with fructose. Transit tolerance was determined at 37 degrees C against simulated gastric juices at pH values of 2.5, 3.0, and 3.5, and against simulated small intestinal juices containing 0%, 0.2%, or 0.4% oxgall. The simulated gastrointestinal transit tolerance of Lactobacillus plantarum strain No. 14 varied with the carbon source. Hence we compared the amounts of exopolysaccharide from Lactobacillus plantarum strain No. 14 cultured in various carbon sources. The exopolysaccharide levels were 146.5+/-8.1 mg/l (culture) with glucose, and 20.1+/-17.0 mg/l (culture) with fructose. When exopolysaccharide was removed by centrifugation, the simulated gastric tolerance of Lactobacillus plantarum strain No. 14 cultured with glucose decreased markedly, but that with fructose did not decrease. These results suggest that the gastrointestinal transit tolerance of Lactobacillus plantarum strain No. 14 is related to exopolysaccharide contents.
