However, soy-product has a defect of low vitamin content, mainly\n the water-soluble vitamin B12. This study was to investigate co-fermentation of glycerol and fructose in soy-yogurt to enhance vitamin B12 production by Lactobacillus reuteri. After a serial combination experiments, the co-fermentation was confirmed to enhance the production of vitamin B12 up to 18 μg/100 mL. Both supplementations induced the expression of cobT and cbiA\n and functioned to balance the redox reaction. Meanwhile, high content \nof fructose supplementation reduced the production of vitamin B12 and suppressed expression of cobT in bacteria. It was proved that the vitamin B12\n content of this soy-yogurt is higher than other fermented soybean based\n food and thus can be served as an alternative food for the aged and \nvegetarians.\n","tracks":[]}
