Streptococcus thermophilus formerly known as Streptococcus salivarius subsp. thermophilus [2] [1] is a gram-positive bacterium, and a fermentative facultative anaerobe, of the viridans group. [3] It tests negative for cytochrome, oxidase, and catalase, and positive for alpha-hemolytic activity. [3] It is non-motile and does not form endospores. [3]
Two essays using lacZ gene targeting PCR primers resulted from this study and were deemed compatible with the two lactic acid bacteria species. This allowed for the direct quantification of Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus in cheese produced from unpasteurized cow's milk. [3]
Yogurt production involves preparing warm milk to a temperature (30–45 °C (86–113 °F)) that will not kill the live microorganisms that turn the milk into yogurt, inoculating certain bacteria (starter culture), usually Streptococcus thermophilus and Lactobacillus bulgaricus, into the milk, and finally keeping it warm for several hours (4 ...
Moreover, the Code of Federal Regulations mandates that in the US, for a product to be called yogurt, it must contain two specific strains of lactic acid bacteria: Lactobacillus bulgaricus and Streptococcus thermophilus, as regulated by the FDA. [18] L. bulgaricus GLB44 is a safe product, without limitations of the quantity consumed.

Curd is made by bacterial fermentation of milk. In this process, lactose in milk is converted into lactic acid by several probiotic microorganisms.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 ...
