Curd is made by bacterial fermentation of milk. In this process, lactose in milk is converted into lactic acid by several probiotic microorganisms.The species involved in the fermentation depends on the temperature and humidity of the environment and may include Lactococcus lactis, Streptococcus diacetylactis, Streptococcus cremoris, Lactobacillus delbrueckii subsp. bulgaricus and ...
Although cows milk curd also is produced, Buffalo curd is the preferred variety. In Nepal, curd is produced by souring pasteurized milk with natural micro-flora. The pasteurized milk is added to a container called theki carved out of wood like Daar(Boehmeria Rugulosa). The milk is left for 12–16 hours and the micro-organisms entrapped within ...
Fermentation of sugars in the milk by these bacteria produces lactic acid, which acts on milk protein to give yogurt its texture and characteristic tart flavor. [2] Cow's milk is most commonly used to make yogurt. Milk from water buffalo, goats, ewes, mares, camels, and yaks is also used to produce yogurt.
The two species work in synergy, with L. d. bulgaricus producing amino acids from milk proteins, which are then used by S. thermophilus. [8] This relationship is considered to be symbiotic. Both species produce lactic acid, [8] which gives yogurt its tart flavor and acts as a preservative. The resulting decrease in pH also partially coagulates ...

The lactic acid produced by the bacterium curdles the milk, which then separates to form curds that are used to produce cheese. [11] Other uses that have been reported for this bacterium include the production of pickled vegetables , beer or wine, some breads, and other fermented foodstuffs like soymilk kefir , buttermilk, and others.

Tibicos water crystals made with Muscovado. This is a list of fermented foods, which are foods produced or preserved by the action of microorganisms.In this context, fermentation typically refers to the fermentation of sugar to alcohol using yeast, but other fermentation processes involve the use of bacteria such as lactobacillus, including the making of foods such as yogurt and sauerkraut.
Many soft cheeses are produced without use of rennet, by coagulating milk with acid, such as citric acid or vinegar, or the lactic acid produced by soured milk. Cream cheese, paneer, rubing, and other acid-set cheeses are traditionally made this way. The acidification can also come from bacterial fermentation such as in cultured milk. [citation ...
