Curd in Indian English is a traditional yogurt or fermented milk product, originating from the Indian subcontinent, usually prepared from cow's milk, and sometimes buffalo milk, or goat milk. L. acidophilus occurs naturally in the human and animal gastrointestinal tract and mouth. It was concluded that applying both L. lactis and S. thermophilus strains would create higher quality reduced-fat cheese with characteristics like those of regular cheese. and is generally used in the production of yogurt, alongside Lactobacillus delbrueckii subsp. L. paracasei is a bacterium that operates by commensalism. In fact, yogurt and cheese that contain live cultures of S. thermophilus are thought to be beneficial to health. USDA statistics from 1998 showed that more than 1.02 billion kilograms of mozzarella cheese and 621 million kilograms of yogurt were produced from S. thermophilus.

Son intérêt économique est majeur, compte tenu de son utilisation dans la fabrication du yaourt ou de certains fromages (Emmental, Cheddar, ...). Postbiotics, the immobilised version of probiotics are gaining traction in recent years due to the concerns about the possibility of low tolerance of probiotics, especially in paediatric populations and in severely ill or immunocompromised patients. When rats were inflicted with mucositis by chemotherapy drugs, the intestinal tissues in those pretreated with streptococcus thermophilus TH-4 functioned more healthily and were less distressed. Lactobacillus forms biofilms in the vaginal and gut microbiota, allowing them to persist during harsh environmental conditions and maintain ample populations.
