Lactobacillus bulgaricus GLB44 Lactobacillus bulgaricus GLB44 "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
Chlamydomonas nivalis "Uredo nivalis". Over the next century, many researchers disputed over whether these organisms were lichen, plants, alga, or animal. It was not until the early 20th century when researchers finally began to agree on the algal nature of the organism and gave its currently known name, "Chlamydomonas nivalis". In 1968 "C. nivalis" was officially recognized as a collective taxon. Unfortunately, due to the lack of sequencing techniques, reliance on visually examining similarly looking snow alga, and complicated life cycle of this species, errors continued to be made in classifying this and other species of snow algae. Today, "C. nivalis" has
