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_113160.1

Its genome

Genome · 2.3 million letters · 32% G+C
Shortest we have Mycoplasmoides genitalium 0.6M
⋮ 507 shorter
Pseudoleptotrichia goodfellowii 2.3M
⋮ 1,844 longer
Longest we have Bradyrhizobium altum 9.8M

Small for a gut microbe: longer than 22% of the 2,354 we have genomes for.

32% G+C, higher than 6% of gut microbes.

To scale: if its ID gene were 1 cm long, its genome would stretch 15 meters. Yours would stretch 21 kilometers. One reference genome; strains vary. NCBI GCF_007990505.1

Capabilities, not measurements of anyone's gut

What it can do

Makes
  • Can make lactic acid What yogurt bacteria make; other microbes turn it into butyrate.
Eats
  • Mixed evidence Can use lactose The sugar in milk and dairy. Genome analysis and published research say yes; lab tests on 2 strains say no.

Not seen in its genomes or lab tests: make butyrate, make propionate, ferment fiber, eat inulin, eat resistant starch, eat pectin, feed on gut mucus, change bile acids, make B vitamins, make hydrogen sulfide, make methane.
