Ingredients for blue cheese 
Most often, moldy cheeses are made from natural cow, goat or sheep milk... A special bacterium is grown for mold growth. For white mold, the bacterium Penicillium Camemberti is used. It only covers the surface of the cheese, without spreading inward.
Blue or greenish mildew - bacteria Penicillium roqueforti - used for Roquefort and Dor Blue varieties. It grows not only on the surface, but also inside the cheeses, creating a marble pattern, a spicy, tangy mushroom flavor.
Cheese with red mold is not for everybody, as they have a rather specific aroma of "unwashed feet". They use the bacterium Brevibacterium linens, it only covers the crust of the cheese.
How to make blue cheese 
Cheeses with noble mold are soft and hard. White cheeses are made by curdling fatty milk, then it is salted and sent to the basement with moldy fungi. The walls of the basement are covered with these bacteria.
Blue cheeses are cooked same curdling, after which the mixture is put into the mold. After a long time, whey drains from the mass. When the product dries up, it is rubbed with salt and stuffed with a special kind of fungus. Then they leave for mold to ripen. 
When the red cheese ripens, it is washed with brine so that it is not covered with common mold. Then the product undergoes a special treatment with fungi, after which a red blurred crust appears.
