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
Luzula nivalis considered L. nivalis to be conspecific with L. arctica, but some of them (Hultén 1968, Böcher et al. 1968) have used the name L. arctica, while the others (Porsild and Cody 1980...) [have used] the correct name L. nivalis.". Elven et al. (2003) also noted that "L. campestris" var. "nivalis" was widely considered to be conspecific with "L. arctica." The current botanical consensus seems to be that lectotypification solves the issue and that "L. arctica" and "L. nivalis" should be regarded as the same species, with the name "L. nivalis" being chosen as this (derived from "L. campestris" var. "nivalis")
