What is the microorganism of Lactobacillus?
Lactobacilli are members of the lactic acid bacteria, a broadly defined group characterized by the formation of lactic acid as a sole or main end product of carbohydrate metabolism. The lactobacilli are gram-positive, non-spore-forming rods or coccobacilli with a G+C content usually below 50 mol% (22).
Are prebiotics living microorganisms?
Probiotics are foods or supplements that contain live microorganisms intended to maintain or improve the "good" bacteria (normal microflora) in the body. Prebiotics are foods (typically high-fiber foods) that act as food for human microflora.

Prebiotics are a source of food for your gut's healthy bacteria. They're carbs your body can't digest. So they go to your lower digestive tract, where they act like food to help the healthy bacteria grow. Probiotics are live yeasts and good bacteria that live in your body and are good for your digestive system.
How do you identify probiotic bacteria?
There are several methods of identifying different probiotic LAB. In this study, the following tests were used: carbohydrate fermentation, gas production from glucose, hydrolysis of arginine, growth at different temperatures, and the resistance to acid and bile salts.
Where does the bacteria in probiotics come from?
A probiotic can be drawn from a human source (cultivated from human intestines or colostrum contained in breast milk), from an animal or dairy source (obtained via the manufacture of yogurt and cheese), or (in fermented vegetables and certain grains such as sauerkraut, kimchi and sourdough bread) and, more rarely, ...
