Lactose intolerance: strains named in the research

Lactobacillus acidophilus is one of the most studied lactic acid bacteria, with research dating back decades documenting its ability to survive the harsh conditions of the gastrointestinal tract, including acid and bile …

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

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

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

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.

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

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

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.

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.

Lactobacillus brevis is a heterofermentative lactic acid bacterium widely distributed in fermented food environments.

Lactobacillus delbrueckii is a lactic acid bacterium widely used in yogurt fermentation and industrial applications.

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

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…

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…

Bacillus licheniformis is a spore-forming bacterium studied in veterinary and aquaculture applications.

Bifidobacterium bifidum is a species naturally present in the human gut, particularly abundant in breastfed infants, where it plays a role in fermenting complex carbohydrates, including human milk oligosaccharides and ce…

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

Bifidobacterium lactis Bi-07 is a well-studied probiotic strain with a body of research spanning in vitro survival assessments, animal studies, and multiple randomized controlled trials (RCTs).

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

Lactobacillus casei Shirota is one of the most extensively studied probiotic strains, with a research history spanning several decades.

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.

Eubacterium rectale is a gram-positive, obligate anaerobe and prominent butyrate-producing member of the human gut microbiota, where it is typically one of the more abundant bacterial species.

Lacticaseibacillus rhamnosus HN001 (formerly classified as Lactobacillus rhamnosus HN001) has been studied across in vitro, animal, and human randomized controlled trial settings.
