Where can I find Lactobacillus Anti-Caries bacteria?
I have to use this type of bacteria for a science experiment. I know that you can find this type of bacteria in yogurt and buttermilk, but I need to have this bacteria by itself, with no other bacteria or living organisms in the source. Please list your source. Please help; my grade depends on finding this out!
How will I know what type of bacteria is the one I want?
I'm not sure how much time you have for this experiment, but pure bacterial cultures are available commercially from many different companies. Some include Presque Isle Cultures, American Type Culture Collection, and Remel. You can purchase the bacteria of your choice (usually for a pretty low price, especially if it's for educational purposes) and they'll ship it to you in 2-3 business days. All of these companies have websites (just Google them) and you can pay online or by phone with a credit card.
Otherwise, I'm not sure how you could achieve a pure culture. Trying to isolate that particular Lactobacillus from yogurt or buttermilk would pretty much be impossible because so many other species are there too.
Hope this helps some!

If you want to get the bacteria by itselve you can streak a plate with yogurt, and incubate it. Any bacteria will grow and then you take the one that you want and you streak a new plate from one colony and when it grows you should be able to see if you only have one type of bacteria.
