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 optimal position in the snow for moisture content, light, and temperature. When in the immotile cyst stage, the "C. nivalis" cells must depend on the flow of meltwater to move it by chance to a favourable area. The temperatures in which this species can survive in ranges from below 0 °C to just above 20 °C. Growth is slow when temperatures are below 5 °C. At 5-15 °C the growth of "C. nivalis" cells can outperform the growth of C. reinhardtii cells. Both species grow at the same rate at 20-25 °C. The growth of "C. nivalis" is suppressed when
