Weissella cibaria is a lactic acid bacterium found in fermented foods and oral environments.

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

Weissella cibaria CMU is an oral probiotic strain (isolated from human saliva) that has been evaluated specifically in the context of oral health.

Bacillus subtilis FW1 is a named isolate of Bacillus subtilis with no strain-specific published evidence in the current indexed literature for probiotic or human health applications.

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

Lactococcus lactis W58 appears primarily in multi-strain probiotic supplement studies rather than as a solo intervention, making it difficult to attribute outcomes to this strain specifically.
