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.
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]
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]

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 ...

Streptococcus is a genus of gram-positive or spherical bacteria that belongs to the family Streptococcaceae, within the order Lactobacillales (lactic acid bacteria), in the phylum Bacillota. [2] Cell division in streptococci occurs along a single axis , thus when growing they tend to form pairs or chains, which may appear bent or twisted.
In addition to boosting the good bacteria, probiotics discourage the growth of harmful, illness-causing bacteria. “Probiotics help maintain an appropriate balance,” Dr. Richter adds.
