Lactobacillus bulgaricus

About :

​

• Lactobacillus bulgaricus is a bacterial subspecies traditionally isolated from European yogurts.

• It is a gram-positive rod that may appear long and filamentous. It is non-motile and does not form spores. It is also non-pathogenic. It is regarded as aciduric or acidophilic, since it requires a low pH (around 5.4–4.6) to grow effectively.

• It has complex nutritional requirements which vary according to the environment. These include carbohydrates, unsaturated fatty acids, amino acids, and vitamins.

​

Uses/Benefits :

​

• Lactobacillus bulgaricus is commonly used as a starter for making yogurt.

• It has also been considered a contaminant of beer due to its homofermentative production of lactic acid, an off-flavor in many styles of beer.

• L.bulgaricus may decrease constipation symptoms.
