Lactobacillus gasseri ATCC 33323

Names Lactobacillus gasseri ATCC 33323
Accession numbers NC_008530
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. Among these, Lactobacillus gasseri appears to represent the major homofermentative Lactobacillus species that occupies the human GI tract. This L. gasseri demonstrates good survival in the GI tract and has been associated with a variety of probiotic activities and roles including reduction of fecal mutagenic enzymes, adherence to intestinal tissues, stimulation of macrophages, and production of bacteriocins. Like other lactic acid bacteria, L.gasseri are acid tolerant, cannot synthesize porphyrins, and possess a strictly fermentative metabolism with lactic acid as the major metabolic end product (adapted from (EBI Integr8)
