Is my starter bubbling from yeast or other gas producing bacteria?
So I made a starter sometime at night. In the morning, I fed it. The next morning it was bubbling and I fed it again. 10 hours later it started gathering a layer of hooch and an acidic smell. Now, I did hear that the first couple days the bubbling is in fact not caused by yeast, but some types of bacteria. And I heard a starter takes more than two weeks to make. So I'm being very pessimistic here and thinking it's most likely not yeast. How can I know the difference?

Can you detect any "off" smell? If it goes from strength to strength then fine. Some starters do depending on certain factors. If however after further feeds it goes quiet then the initial bubbling up was of the bad bacteria. Trick is to slow your feedings down at this stage and pick them up again when your starter picks up again. See what happens over the coming days.
