Answer 1

Well, i really don't understand the last part, but i can tell you that the answer is lactic acid fermentation, because as lactic acid hardens, and thickens, you get either sour cream or yogurt. ( they form from curts)

We can look for SACCHAROMYCES CEREVISIAE for alcoholic fermentation....
