Abstract:
The present invention relates to a culture medium containing D-tagatose and a method of verifying carbon source utilization of human intestinal bacteria using the same. The present invention has an excellent effect of growing selectively only a Lactobacillus casei which is useful lactic acid bacteria in the human body intestines without growing harmful intestinal bacteria of the human body by providing the culture medium containing the D-tagatose as a carbon source.
