How is bacteria useful for making curd?

The Lactobacillus bacteria grow on lactose and produce lactic acid as a byproduct of fermentation. The lactic acid produced decreases the pH of the milk which curdles the milk protein casein. Homemade curd contains several species of the Lactobacillus like L.

Which bacteria is used in curd?

Curd may contain a wide variety of bacteria like Lactobacillus acidophilus, Lactococcus lactis, Lactococcus lactis cremoris etc, whereas yoghurt contains Streptococcus thermophillus and Lactobacillus bulgaricus.

How does the bacterium Lactobacillus help in curd information?

Lactobacillus (present in curd) converts sugars in milk (Lactose) into lactic acid. Lactic acid imparts sour taste to curd. Increased acidity causes milk proteins (casein) to turn into solid masses. This changes the texture of curd.

Which bacteria helps in fermentation of curd?

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 Streptococcus thermophilus.

Which bacteria help in making the curd from milk?

Milk converts to curd due to the production of lactic acid. This process of conversion of milk to curd occurs due to the action of bacteria Lactobacillus that form lactic acids from sugars present in the milk. Lactobacillus is a genus of Gram- positive bacteria, anaerobes that are rod- shaped, and do not form spores.

Which bacteria helps in conversion of milk into curd?

When Lactococcus lactis is added to milk, the bacterium uses enzymes to produce energy (ATP) from lactose. The byproduct of ATP production is lactic acid. The lactic acid curdles the milk that then separates to form curds, which are used to produce cheese and whey.

What can bacteria have?

Bacteria are single celled microbes. The cell structure is simpler than that of other organisms as there is no nucleus or membrane bound organelles. Instead their control centre containing the genetic information is contained in a single loop of DNA.
