Abstract
We have investigated the survival and activity of GanedenBC30 during passage through the upper gastro-intestinal tract. GanedenBC30 was tested in a dynamic, validated, in vitro model of the stomach and small intestine (TIM-1) on survival and its potential to aid in digestion of milk protein, lactose and fructose. The survival of GanedenBC30 was high (70%), although germination of the spores was minimal (<10%) under the conditions tested. Survival of the strain in the presence of lactose and fructose was markedly lower (56-59%) than in the absence of the sugars. The amount of digested milk protein available for absorption was somewhat higher (+0.2 g) when GanedenBC30 was added to the milk. When GanedenBC30 was tested with lactose or fructose added to the meal, the cumulative amount of lactate produced was slightly higher (+0.12-0.18 mmol) compared to the GanedenBC30 alone. In conclusion, although the differences in survival of GanedenBC30 are small, these results show the potential of GanedenBC30 to aid in protein digestion and in the digestion of lactose and fructose. If a larger fraction of the Bacillus coagulans cells had germinated, the influence on protein and carbohydrate digestion would probably have been much greater. Importance of the findings: the potential of GanedenBC30 to aid in the digestion of lactose and fructose could be used to prevent occurrence of intestinal symptoms in individuals sensitive to these carbohydrates.
