S
accharomyces boulardii
is emerging as potential
probiotic organism. This yeast has shown promising
results in preventing enteral nutrition-related diarrhea,
acute gastroenteritis, traveler’s diarrhea and decreasing
Helicobacter pylori
treatment-related symptoms. The
role of S. boulardii for both the prevention of Antibiotic-
associated diarrhea (AAD) and treatment of irritable bowel
syndrome and recurrent
C. difficile disease
, Crohn’s disease,
and giardiasis has been clearly demonstrated. Probiotic
yeast has been considered superior over probiotic bacteria
because of the natural resistance of yeast to antibacterial
antibiotics. Probiotic yeasts have also shown a positive
effect on poultry health and nutrition by reducing lactic acid
acidosis, increasing fiber digestibility, secreting enzymes and
improving animal performance by enhancing their growth
rate and increasing milk, meat and eggs production. In the
present study,
Saccharomyces cerevisiae
Id18 isolated from
traditional Indian fermented food – Idli batter, exhibited
probiotic attributes such as acid and bile salt tolerance, ability
to grow at 37ºC, resistance to commonly used antibiotics,
auto-aggregation ability and cell surface hydrophobicity.
It showed antimicrobial action against enteric pathogens.
It produced phytase, β-galactosidase, vitamin B12 and
exopolysaccharides. It had the ability to assimilate
cholesterol
.
This probiotic yeast, when used either alone
or in combination with traditional dairy starter, significantly
improved the nutritional properties and the shelf life of the
fermented dairy product.
