We investigated the yogurt starter cultures of Lactobacillus bulgaricus 151 and Streptococcus thermophilus MK-10 for their effect on the severity of experimental colitis, lymphocyte profile, and regulatory T-cell response. bulgaricus and/or L. helveticus . bulgaricus is a component of “thermophillic” starter cultures used in the manufacture of a number of fermented dairy products (Hassan and Frank, 2001). 100% potency guaranteed. Lactobacillus bulgaricus (L. bulgaricus) was originally discovered in 1905 as a crucial element of Bulgarian yogurt by Dr. Stamen Grigorov. He attributed some general health benefits to it. L. delbrueckii subsp. Strength: 1 gram of starter contains more than 25 billion cfu of lactic acid probiotic bacteria strains lactobacillus bulgaricus and streptococcus thermophilus. However, many yogurt producers and starter culture makers include Lactobacillus acidophilus and/or Lactobacillus lactis. Our research has shown that this composition harms the quality, taste and flavor of the end products and results in a blander, generic taste of the yogurt. Ingredients: Live active lactic acid cultures (lactobacillus bulgaricus and streptococcus thermophilus) Type: Heirloom Bulgarian yogurt starter. These cultures have an optimum growth temperature of approximately 42oC and contain Streptococcus thermophilus with L. delbrueckii subsp. Traditionally, Bulgarian yogurt is made using starter culture containing two strains — Lactobacillus delbrueckii ssp. We investigated the yogurt starter cultures of Lactobacillus bulgaricus 151 and Streptococcus thermophilus MK-10 for their effect on the severity of experimental colitis, lymphocyte profile, and regulatory T-cell response. Colitis was induced in BALB/c mice via the administration of 3.5% dextran sul … Colitis was induced in BALB/c mice via the administration of 3.5% dextran sulfate sodium salt (DSS) in drinking water for 6 d. Since then, numerous studies have shown that it is not only one of the two bacteria required for yogurt, but it has numerous beneficial probiotic properties in the human body. bulgaricus and Streptococcus thermophilus.
