The same reason that cheese and sour cream are preserved: all of these products are made from milk that is mixed with various bacterial cultures. These cultures change the milk into a new product in which fermentation occurs instead of spoiling. Fermentation is also the process that preserves wine where fruit juice would spoil.
The microorganisms that exist in fermented products (sourdough bread dough is another) keep the oxygen cycle working to keep the food fresh. Fermentation is an ancient process used by many cultures world wide to create food that has a longer shelf life. Beer uses this process too, as does sourkraut.

Can you use all purpose cream as an alternative to whipping cream when making yogurt?
Recipes I have used, and that came with my yogurt maker say you can use: Whole milk 2% milk 1% milk Fat free milk Soy Milk or Almond milk to make yogurt. I have never seen a recipe using cream for yogurt making. So I think all purpose cream would make a heavy yogurt and so would whipping cream. When I made yogurt using 2% milk it is much lighter than yogurt make with whole milk and takes longer to cure. The yogurt maker suggested 10 hours for whole milk yogurt and 12 hours for 2% yogurt. Good luck.

In order to get the proper yogurt culture to grow, the other possible competing cultures, yeasts and bacteria must be removed, which is done by pasteurizing. This creates a sterile controlled medium to grow the yogurt in.
What type of organisms are in sour cream?
Well, to make sour cream, I dont know. But to make yogurt is Bacteria. "Yogurt production demonstrates fermentation by Streptococcus thermophilum and Lactobacillus bulgaricus. Heated milk is inoculated and maintained at a given temperature causing bacteria to grow and ferment lactose, the sugar in milk. The bacteria produce lactic acid which causes the milk to coagulate and adds a sour flavor." (from www.uwrf.edu/biotech/workshop)
