In Lactobacillus acidophilus, which can be found in the gastrointestinal tract, quorum sensing is important for bacterial interaction when considering biofilm formation and toxin secretion. [14] In L. acidophilus , along with many other bacteria, the luxS -mediated quorum sensing is involved in the regulation of behavior.
Lactobacillus is a genus of gram-positive, aerotolerant anaerobes or microaerophilic, rod-shaped, non-spore-forming bacteria. [2] [3] Until 2020, the genus Lactobacillus comprised over 260 phylogenetically, ecologically, and metabolically diverse species; a taxonomic revision of the genus assigned lactobacilli to 25 genera (see § Taxonomy below).

Lactic acid bacteria are used in the food industry for a variety of reasons such as the production of cheese and yogurt products. Popular drinks such as kombucha are made using lactic acid bacteria, with kombucha having been known to have traces of Lactobacillus and Pediococcus once the drink is made. [23]
Lactobacillus bulgaricus and Streptococcus thermophiles are commonly used to ferment milk to form yogurt, but many other bacterial strains, or probiotics, may also be added.
In 1920, Rettger and Cheplin reported that Metchnikoff's "Bulgarian Bacillus", later called Lactobacillus delbrueckii subsp. bulgaricus, could not live in the human intestine. [70] [non-primary source needed] They conducted experiments involving rats and humans volunteers, feeding them with Lactobacillus acidophilus.
Bifidobacterium is a bacterium that is normally found in yogurt. The study found that those who ate yogurt at least twice a week had "lower incidence of Bifidobacterium-positive proximal colon ...
Yogurt typically lasts beyond its “best by” date, but it does spoil. If your expired yogurt smells, tastes, or looks funny, throw it away. If Your Yogurt Has A Lot Of Liquid At The Top, Sniff ...
