A sourced index of probiotic strains and the research that names them.
A dedicated index of probiotic-strain research, built from 220k papers. Its own corpus, separate from the rest of Winnow's research. Different papers, different questions. Made for researchers, formulators, and curious readers.

Akkermansia muciniphila MucT
Akkermansia muciniphila MucT is the type strain (the reference isolate) of a gut bacterium that lives in and feeds on the mucus layer lining the intestine.
Akkermansia muciniphila EB-AMDK19
Akkermansia muciniphila EB-AMDK19 is a bacterium belonging to the Akkermansia genus, a member of the Verrucomicrobia phylum.
Akkermansia muciniphila
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.
Bacillus aerius
Bacillus aerius is an environmental and thermophilic bacterium studied primarily for its industrial enzyme production, including lipases, endoglucanases, and keratinases, rather than for human health applications.
Bacillus albus
Bacillus albus is a spore-forming environmental bacterium whose published research base is dominated by soil ecology, bioremediation, and agricultural applications rather than human probiotic science.
Bacillus albus E1-4
Bacillus albus E1-4 is a recently reclassified environmental Bacillus strain — B.
