Lactobacillus LB

[modifier | modifier le code]

Lactobacillus LB is a postbiotic product obtained by co-fermentation of two bacterial strains (Limosilactobacillus fermentum - previously called Lactobacillus fermentum - and Lactobacillus delbrueckii) followed by heat treatment and subsequent drying in presence of spent culture medium.

Postbiotics are defined by the International Scientific Association for Probiotics and Prebiotics as “a preparation of inanimate microorganisms and/or their components that confers a health benefit on the host”[1]. Postbiotics contain key components such as inactivated microbial cells, cell fragments, and metabolites. Despite being inanimate, they confer similar, or sometimes even more potent health benefits compared with probiotics, a phenomenon called the “probiotic paradox”.
