Lactobacillus delbrueckii subsp. bulgaricus Lactobacillus delbrueckii subsp. bulgaricus Lactobacillus delbrueckii" subsp.

First identified in 1905 by the Bulgarian doctor Stamen Grigorov, the bacterium feeds on lactose to produce lactic acid, which is used to preserve milk. "Lactobacillus delbrueckii" subsp. "bulgaricus" can be found naturally in the gastrointestinal tract of mammals living in Bulgaria, but one specific strain, "Lactobacillus bulgaricus" GLB44, is extracted from the leaves of the "Galanthus nivalis" (snowdrop flower) in Bulgaria as well.

Micranthes nivalis Russia, Canada, Alaska and Greenland. The plant was first described by Carl Linnaeus in "Flora Lapponica" (1737), as a result of his Lapland voyage. Some populations from the Canadian Province of Quebec have been recognized as a distinct species by some authors, a variety of "M. nivalis" others: is distinguished from var. "nivalis" by smaller inflorescences and narrower leaves. It is known only from the Shickshock Mountains of the Gaspé Peninsula of southeastern Québec. It has been suggested that this may be a hybrid of "M. nivalis" and "M. tenuis;" further study is warranted. Micranthes nivalis Micranthes nivalis is a
