what is s thermophilus grown
Streptococcus salivarius subsp. thermophilus (previous name Streptococcus thermophilus) is a gram-positive bacteria and a homofermentative facultative anaerobe, of the viridans group.It tests negative for cytochrome, oxidase and catalase, and positive for alpha-hemolytic activity.. thermophilus is found in fermented milk products, and is generally used in the production of yogurt, alongside Lactobacillus delbrueckii subsp. bulgaricus. The two species are synergistic, and S. thermophilus probably provides L. d. bulgaricus with folic acid and formic acid which it uses for purine synthesis.
Introduction. Streptococcus thermophilus belongs to the thermophilic group of lactic acid bacteria. It is traditionally used in association with one or several Lactobacillus species as a starter culture in the production of yogurt and the manufacture of Swiss and Italian cheeses such as Emmentaler and Mozzarella.n common with other lactic acid bacteria, some strains of S. thermophilus produce exocellular polysaccharides (EPS). The EPS produced by S. thermophilus is critically important for the final texture in most yogurt processes.
