Lactobacillus bulgaricus
Lactobacillus delbrueckii subsp. bulgaricus (tidligere Lactobacillus bulgaricus) er en gram-positiv bakterie af slægten Lactobacillus (og er derfor en stavformet, fakultativt anaerob, ikke-sporedannende bakterie). Den er en mælkesyrebakterie og anvendes bl.a. sammen med Streptococcus thermophilus til fremstillingen af yoghurt, hvor den under fermentering omdanner lactose til lactat, der under afgivelse af en hydron omdannes til mælkesyre. Dette er både for at forlænge holdbarheden og skabe den ønskede smag. Den findes også i mælk, hvor dens fermentering kan gøre den sur.

These are popular lacto bacterias to make yogurt I use at home. They are named in spanish "bacilos bulgaros" (bulgarian bacillus). I am not sure this bacteria is whose specific scientific named is "Lactobacillus_bulgaricus". Photo was taken with a digital conventional camera with simple "close-up", any other amplification was used.
