Lacticaseibacillus rhamnosus GG (LGG) is one of the most extensively studied probiotic strains globally, though the papers linked to this strain entry focus primarily on encapsulation technology and formulation stability…

Limosilactobacillus reuteri DSM 17938 (formerly Lactobacillus reuteri DSM 17938) has been studied in multiple randomized controlled trials and at least one published meta-analysis examining infantile colic, episodes of p…

Bifidobacterium longum is a well-characterized commensal species found throughout the human gut, with a particularly studied role in early-life microbiome establishment.

Lactiplantibacillus plantarum (formerly Lactobacillus plantarum) is a well-characterized lactic acid bacterium found across fermented foods, the human gut, and diverse environmental niches.

Bifidobacterium infantis is an anaerobic bacterium native to the infant gut microbiota.

Lacticaseibacillus rhamnosus, most widely studied as the GG strain, has an extensive research record, though the evidence base in this index is predominantly in vitro and animal-model work.

Bacillus coagulans is a spore-forming bacterium studied as a probiotic candidate, in part because its spores exhibit heat and acid stability, a property studied in relation to survival through food processing and gastric…

Clostridium butyricum is a spore-forming anaerobic bacterium capable of producing butyric acid through fermentation.

Lactobacillus casei (species-level entry, undesignated strain) is a broadly studied lactic acid bacterium encountered across fermented dairy and non-dairy foods.

Lactobacillus plantarum 299v is one of the more studied probiotic strains in its species, with research spanning in vitro cell-interaction studies and observational work in human subjects.

Bifidobacterium infantis 35624 (also marketed as Bifantis) is one of the more thoroughly studied probiotic strains in the Bifidobacterium genus.

Bifidobacterium breve is a species commonly found in the human gut, particularly in breastfed infants, where it plays a role in fermenting complex carbohydrates including human milk oligosaccharides.

Akkermansia muciniphila is a gut bacterium that naturally inhabits the mucus layer lining the intestine and has attracted substantial scientific interest as a potential next-generation probiotic.

Bifidobacterium animalis BB-12 is one of the most extensively studied Bifidobacterium strains, with a research record spanning food science, gut physiology, and clinical settings.

Escherichia coli Nissle 1917 (EcN) is a non-pathogenic E.

Faecalibacterium prausnitzii is a butyrate-producing commensal bacterium that is among the most abundant in a healthy human gut and has attracted significant research interest as a potential next-generation probiotic.

Lacticaseibacillus casei (species-level entry, no specific strain designation) is a broad species grouping that includes well-studied commercial strains such as L.

Lacticaseibacillus paracasei (the species, without a designated strain identifier) is a broadly distributed lactic acid bacterium found in fermented foods and the human gut.

Lactobacillus acidophilus NCFM is a well-characterized probiotic strain studied across a range of laboratory and animal model contexts.
