"This is the first map of what the microbial diversity of sourdoughs looks like at this scale, spanning multiple continents," says Elizabeth Landis. "And we found that where the baker lives was not an important factor in the microbiology of sourdough starters." (Credit: Lauren Nichols)

I'm surprised this thread doesn't get more success  :-D

I like the clipped page but don't enjoy being called crazy  :)

I posted this a while back:
https://www.nytimes.com/2020/04/11/science/sourdough-bread-starter-library.html?action=click&module=Editors%20Picks&pgtype=Homepage

"Afterward, researchers swabbed the bakers’ washed hands and cultured the microbes. The conclusion reversed the expectation: The microbes on the hands of the bakers mirrored the microbes within their starters. The bakers had become their bread. “The bakers’ hands reflect the life they have lived,” observed Dr. Dunn, “a life with their fingers and thumbs in dough.”

In addition to yeast and bacteria, sourdough harbors many secrets. One is whether very old starters retain microbes from the person who made them. “Does the starter you got from your grandmother still have some of her body microbes?” asked Dr. Dunn. “Is your grandmother alive in the starter she gave to you? I think that we will find that in some cases the answer is yes.”

Very interesting!
It would be great if their studies showed if a second SD, made with exactly the same flour/water/T°/tools as the first one, would yield the same micro-flora or not. Do you guys know if a study about it exists?

https://www.scientificamerican.com/article/the-science-of-sourdough-how-microbes-enabled-a-pandemic-pastime/

In one recent study, Madden and her colleagues shipped bags of the same flour to 18 professional bakers around the world, who then used the flour to create starters in their own kitchens using identical techniques.* About a month later, the bakers and their starters convened in Belgium, where researchers used DNA sequencing to identify the microbes in each starter.

This is great- thanks for posting. To paraphrase the late congressman Tip O’Neill: “all sourdough is local”.
