February 24/London/Hindustan Times -- Probiotics are bugs known to promote health, but only some are able to survive the harsh environment of the human digestive tract. For instance, the lactobacilli strains showed the highest survival rate in the “model digestive system,” which mimics the human digestive system, developed by a team from the Norwegian University of Life Sciences, as compared to other strains of probiotic bugs. They also found that some of these strains survive better when consumed as fermented milks, the Journal of Dairy Science reports.
The initial testing in acid and bile salts found that Lactobacillus strains had a significantly higher acid tolerance than the lactococci strains and E. hirae, according to a Norwegian statement.
