yeast
Yeast and bacteria are the two main types of microbes that can cause fermentation. Yeast, such as Saccharomyces cerevisiae, is commonly used in bread making and beer brewing. Lactic acid bacteria, such as Lactobacillus, are often used in fermenting dairy products like yogurt and cheese.
sac fungi "a packet of baking yeast holds spores of the sac fungus saccharmyces cerevisiae. when bread dough is set out to rise in a warm place the spores germinate and release cells that reproduce by budding. bubble of carbon dioxide produced by the fermenation of reactions in these cells cause dough to expand. fermentation by s. cerevisia also helps us produce beer and wine" straight from the biology book
Nutritional values of food products differ between manufacturers. Nothing in "white bread" should cause such a severe effect without allergy.
Enzymes in milk do not typically cause citric acid. Citric acid is a naturally occurring organic acid found in citrus fruits or produced through fermentation. Enzymes in milk, such as lactase or lipase, are responsible for breaking down lactose or fats, respectively, but not for citric acid production.
Lactic acid is a type of organic acid that forms during anaerobic fermentation, such as during vigorous exercise when oxygen supply is limited. It is produced in muscles and can cause muscle fatigue and soreness. Lactic acid is also produced during the fermentation of certain foods like milk into yogurt.
Yeasts are used to change sugar into alcohol and carbon dioxide and this process is known as Fermentation. Wine and beer are also made this way. Beer is produced by fermenting germinating cereals , while wine is produced by fermenting crushed grapes. Yeasts are also used to ferment bread and cause it to rise (the alcohol produced by the fermentation is evaporated in the baking). Yeasts are present in the air, especially near a place where bread has been made, so fruit juices left in the open in your kitchen will naturally ferment into wine.
The sour taste in yogurt and some cheeses is caused by lactic acid, which is produced by bacteria fermenting lactose, a sugar found in milk. This fermentation process gives these dairy products their tangy flavor.
I have the same question, and I think it's because muscles have the gathering and building up of Lactic Acid, while bread has air pockets of carbon dioxide, so one is storing it up, the other is holding it in.
Fermentation occurs when living cells present on the skin of fruit and vegetables break down the sugars inside. Microorganisms called yeasts do this job in the main. They grow under varied conditions and produce different end products, the main by products being alcohol and carbon dioxide.When wet, yeast feeds on sugar, creating carbon dioxide bubbles, which causes bread to rise, or ferment.
If an organism oxidatively metabolizes glucose the result that will occur in the fermentation tube is yellow. In fermentation, when not enough carbohydrates is added, the bacteria will digest peptones as their carbon source.
There is archaeological evidence that fermentation was discovered when grain in a container accidentally got wet. It was then used to make a primitive beer (just grain, yeast, and water - no hopps). Later it was applied as a leavening in breads.
