Lactobacillus delbrueckii subsp. bulgaricus ATCC BAA-365

Names Lactobacillus delbrueckii subsp. bulgaricus ATCC BAA-365
Accession numbers NC_008529
Background Lactobacilli are normal inhabitants of the gastrointestinal tract of man and animals where they are widely considered to exert a number of beneficial roles including immunomodulation, interference with enteric pathogens, and maintenance of a healthy intestinal microflora. Historically, probiotic roles have been ascribed primarily to Lactobacillus acidophilus. The genus Lactobacillus presently comprises more than 50 recognized species of non pathogenic bacteria which in addition to their probiotic effects are useful to human as indispensable agents for the fermentation of foods and feed. Lactobacillus delbrueckii subsp. bulgaricus (strain 2038) is a facultative aerobic, thermophilic Gram-positive bacterium. It is used as a starter culture for a number of fermented dairy products such as yogurt and Swiss and Italian-type cheeses. The optimum temperature for growth is 42 degrees Celsius. The specific physiological properties of L.delbrueckii subsp. Bulgaricus are lysine biosynthesis, formate production, aspartate-related carbon-skeleton intermediate metabolism, unique EPS synthesis and efficient DNA restriction/modification systems, which are all different from those of the collection strains that might benefit the industrial production of yogurt. Its efficient protocooperation with Streptococcus thermophilus and lactate production as well as well-equipped stress tolerance mechanisms may account for it being selected originally for yogurt fermentation industry.
