Propionibacterium freudenreichii is a gram-positive, non-motile bacterium that plays an important role in the creation of Emmental cheese, and to some extent, Jarlsberg cheese, Leerdammer and Maasdam cheese. Its concentration in Swiss-type cheeses is higher than in any other cheese.
Food microbiology is the study of the microorganisms that inhabit, create, or contaminate food.This includes the study of microorganisms causing food spoilage; pathogens that may cause disease (especially if food is improperly cooked or stored); microbes used to produce fermented foods such as cheese, yogurt, bread, beer, and wine; and microbes with other useful roles, such as producing ...
Clostridium tyrobutyricum spores present in raw milk ferments lactate causing the "late-blowing" defect in high-pH cheeses such as Emmentaler, Gouda or Edammer.Even low spore densities of this anaerobe in milk used for cheese production can bring about this phenomenon, if the growth conditions are suitable.

Microbial food cultures are live bacteria, yeasts or moulds used in food production. Microbial food cultures carry out the fermentation process in foodstuffs. Used by humans since the Neolithic period (around 10 000 years BC) [1] fermentation helps to preserve perishable foods and to improve their nutritional and organoleptic qualities (in this case, taste, sight, smell, touch).
These bacteria are chosen because they produce exopolysaccharide (EPS), which give reduced-fat cheese a texture and flavor like that of regular cheese. [citation needed] L. lactis produces cheese with higher moisture levels compared to other reduced-fat cheeses; S. thermophilus produces cheese with a lower moisture content and a less bitter taste.
Lactobacillus helveticus is a lactic-acid producing, rod-shaped bacterium of the genus Lactobacillus.It is most commonly used in the production of American Swiss cheese and Emmental cheese, but is also sometimes used in making other styles of cheese, such as Cheddar, Parmesan, Romano, provolone, and mozzarella.
Lactococcus lactis is a gram-positive bacterium used extensively in the production of buttermilk and cheese, [1] but has also become famous as the first genetically modified organism to be used alive for the treatment of human disease. [2]
