curd contain lactobacillus which can be stained with simple stain i.e. methylene blue which will stain it in blue colour and also can be stained with gram stain as lactobacillus is gram +ve so it will give again blue colour in gram stain.
Yogurt (curd) is added to idli and bhatura batter as a fermenting agent. The bacteria in the curd help in the fermentation process, which creates a light and fluffy texture in idlis and bhaturas. This also helps in making the final dish more digestible.
Curd is added while making idlis to enhance fermentation, which is crucial for achieving the light and fluffy texture characteristic of idlis. The lactic acid bacteria in curd promote the fermentation process, helping to leaven the batter. Additionally, curd contributes to the flavor and nutritional value of the idlis, making them softer and more palatable.
The bacteria present in curd are primarily Gram-positive bacteria. These include species like Lactobacillus acidophilus and Streptococcus thermophilus. Gram-negative bacteria are not typically found in curd as the fermentation process favors the growth of Gram-positive bacteria.
Curd is not considered a pure substance; it is a mixture. It contains water, proteins, fats, lactose, and various microorganisms, such as bacteria, which contribute to its texture and flavor. The composition of curd can vary depending on factors like the type of milk used and the fermentation process, making it heterogeneous.
Rennin deactivate the casein micelles in milk, causing a distinct separation of curd protein (solid) and whey protein (liquid).

Formation of curd in milk is called 'Fermentation'.Curd is formed when milk is pasteurised and fermented by a combination of lactic acid bacteria and a protease.

The composition of curd can vary depending on factors like the type of milk used and the fermentation process, making it heterogeneous.
Curd does not typically contain yeast; it is primarily made through the fermentation of milk by specific bacteria, mainly lactic acid bacteria. These bacteria convert lactose into lactic acid, which thickens the milk and gives curd its tangy flavor. While yeast can be present in some fermented dairy products, it is not a standard component of traditional curd.
Curd contains live bacteria that continue to ferment the milk sugars even after it has set. If the curd is not transferred to a cool place, the bacteria will continue to multiply and produce more lactic acid, causing the curd to become increasingly sour.
Curd is added while making idli and bhatura dough as curd contains Lactobacillus bacteria that undergoes anaerobic respiration and in this process it acts on sugar of the flour and releases carbon dioxide gas, this gas make the dough rise and when baked or fried gas escapes leaving the idli or bhatura soft and spongy.
The bacteria (Lactobacillus) needs warmth to convert milk to curd. So the setting of curd is faster in summer.
because the bacterias does not feed on us. But without them we cannot get food, there will not be any decomposition in our surroundings. For example in the matter of foo we can take the example of curd. for making curd, first we need milk but after taking the milk for converting it into curd there must be the micro organism yeast. so we humans cannot live without the bacterias
