In the present study, we utilized lactic acid bacteria and germinated soybean with high GABA-genereting capacity and developed yogurt with enhanced levels of GABA, isoflavones and some amino acids. It has been reported that GABA synthesis in plants is controlled by various external factors, e.g., physical stimulus, temperature, hypoxia, moisture, stress, etc. Thus plants, it may be suggested, utilize the GABAgenerating system to cope with environmental stress,
