You can buy some of that Lactobacillus species from ATCC: https://www.atcc.org/products/27651 They also sell bacterial pathogens and other things useful for researchers, so that's pretty interesting (at least to me). I never really think about the overlap of food and microbes.

It's also called Fructilactobacillus sanfranciscensis in some places. I can't quickly tell which is the more recent naming and what lead to that change. It's lactic acid bacteria regardless.

Thanks for proving me wrong! Good to get something more than anecdote :))
