So under most brewing conditions a nonzero amount of this microbe survive, but that count is 3 orders of magnitude lower what might be termed a “therapeutic dose?”
What even is a good experimental design for probiotic tea? Brew -> agitate in hydrochloric acid & digestive enzymes for X minutes -> mix with billions of existing gut microbes (that may kill this microbe or out-compete it for resources) and incubate at body temperature -> count the number of new colonies of this particular microbe?
That was a fun read. The author has a really good storytelling style.
I dont understand why the cold brew test had fewer bacteria than the steeped teas. If the bacteria are shielded in spores, shouldnt it be expected that they have the same amount of bacteria?
I think it’s just that the bacteria in the hotter container woke up to a warmer, nicer environment. Warm temperatures are much better for bacterial growth. While it was too hot they didn’t seem to care at all since their spores protect them completely from damage.
This almost throwaway line from the article struck me as an example of what we can do with technology, if we choose to put our billions of dollars towards it: "I downloaded the BC30 genome".
Another organism that survives pasteurization is paratuberculosis, in milk. It is commonly found in commercial dairy herds. In my opinion, this is alarming.
Many consider it to be a candidate for the cause of Crohn’s disease. Johne’s disease, which occurs in a subset of cattle infected by paratuberculosis, bears many similarities to Crohn’s disease.
When Crohn’s disease was first described, it was believed to be an intestinal tuberculosis, though tests seemed to counter this idea; to this day, it remains difficult to test humans for paratuberculosis infections.
Cool story with an interesting ending (to me at least).
Just a tiny nit... Should "Brewed as directed for 4 minutes in boiling water." be "Brewed as directed for 4 minutes in boiled water." Was the tea sitting in water that was boiling or placed in water that just boiled? The later is how I brew my teas.

They could have some coating that make them stick to the content of the tea bag, basically affecting their solubility.

What’s even more shocking to me: one can “3D-print” downloaded genome, too! What a time to be alive.

Left in previously boiled water for 4 min. We can deduce this from the second sample, which simulates forgetting your tea bag in the mug for 15 min.
Isn't boiled water what goes up into the air?
I boiled water today and survived.
Interesting… did you boil the water with you inside of it?
