Are microorganisms used in the production of butter?


Microorganisms are needed to produce yoghurt, but not butter. When you buy milk that is not homogonized (may be hard to get in the city) you will see the fat of the milk separates from the watery part: it floats on top. When you skimm that, and beat it for a while, the fat turns into butter (churning). That is all. Salt may be added, and in industrial production the fat/water content is controled, but basically butter consists of milk fat only.
