Its ID gene: the stretch scientists read to tell microbes apart. Each bar is one letter of its DNA. Every species has its own order of letters, so the pattern works like a fingerprint. Close relatives share most of it.
16S rRNA gene, V4 region: the 253 letters between the standard primers (515F/806R), which are the same in every species. One reference sequence; strains can differ by a letter or two. NCBI NR_029133.1
Formerly Lactobacillus pentosus.
Mid-sized for a gut microbe: longer than 63% of the 2,354 we have genomes for.
46% G+C, higher than 46% of gut microbes.
To scale: if its ID gene were 1 cm long, its genome would stretch 24 meters. Yours would stretch 21 kilometers. One reference genome; strains vary. NCBI GCF_003641185.1
What it can do
- Can make lactic acid What yogurt bacteria make; other microbes turn it into butyrate.
- Can ferment fiber Breaks down dietary fiber that our own enzymes can't.
- Can use lactose The sugar in milk and dairy.
Not seen in its genomes, lab tests or published research: make butyrate, make propionate, eat inulin, eat resistant starch, eat pectin, feed on gut mucus, change bile acids, make B vitamins, make hydrogen sulfide, make methane.
All 13 capabilities and their evidence
| Capability | Verdict | Genome analysis | Lab tests | Published research |
|---|---|---|---|---|
| Can make butyrate | Not seen | 0 of 1 genome | — | No papers |
| Can make propionate | Not seen | 0 of 1 genome | — | No papers |
| Can make lactic acid | Can | 1 of 1 genome | — | Papers say yes |
| Can ferment fiber | Can | 1 of 1 genome | 0 of 5 strains · strip test Strip tests often miss fiber-eaters, so this doesn't override the genomes. | Papers say yes |

Strains studied
How much each strain has been studied in people, not whether it works. Many trials test a strain inside a blend, so those are counted apart, and reviews are summaries of trials, so they're never counted as more trials.
