Lactobacillus delbrueckii subsp. bulgaricus is a bacterial subspecies traditionally isolated from European yogurts.Lactobacillus bulgaricus GLB44 differs from the rest of the L. bulgaricus strains as it was isolated from the leaves of Galanthus nivalis (snowdrop flower) in Bulgaria, becoming the only known strain of this subspecies that has vegan origin (not from yogurt) available as a commercial probiotic. Probiotics are health promoting bacteria which, when consumed in adequate amounts, confer a benefit on the host, normally associated with positive effects on the digestive and immune systems, and are usually prescribed during or after antibiotic treatment to alleviate the symptoms of antibiotic-associated diarrhea. Probiotics are also associated with decreasing of the risk of traveler’s diarrhea. The natural habitat of the snowdrop flower are European mountainous regions. Thus, GLB44 is capable of surviving in freezing temperatures, as the snowdrop flowers between January and May in nature, when the temperatures can fall below freezing in this region. These characteristics of its natural habitat allows for GLB44 to survive in foods that are plant based and remain unaffected when stored in refrigerator temperatures.
GLB44 has inhibitory qualities against bad bacteria such as E. Coli and Salmonella spp. A research study was completed by a Harvard Medical School professor at Brigham and Women's Hospital, Andrew B. Onderdonk, PhD. The study has revealed GLB44's strength and effectiveness against bacterial pathogens. GLB44 has patent pending status in the US for its pathogen inhibitory qualities in vegan foods.
All other commercially available strains of L. bulgaricus are isolated from traditional yogurts and are grown in milk. Distinctly from the other L. bulgaricus, GLB44 grows very well in vegetable juices, given its natural plant habitat. Since all probiotics carry some of the organic matter in which they are grown, GLB44 carries traces of vegetable juice. GLB44 is currently grown in the European Union, in vegetable juice sourced from European farms that are GMO free.
