Abstract
The present invention relates to compositions comprising galactooligosaccharides (GOS) and probiotic bacteria obtained by a process comprising the step of growing the bacteria in a medium comprising GOS, such composition having the effect of boosting the synbiotic effect of the probiotic bacteria with the GOS. Health benefits of the probiotic bacteria as obtained by such a fermentation process are also contemplated.
Claims20
A composition comprising an effective amount of galactooligosaccharides and a probiotic bacteria comprising the galCDEGR(A) operon, wherein the probiotic bacteria is obtained by a process comprising
- fermenting the probiotic bacteria in a bacterial growth medium comprising galacto-oligosaccharides, peptone, and at least one of 3′-sialyllactose or 6′-sialyllactose;
- harvesting the fermented probiotic bacteria, and
- adding additional galacto-oligosaccharides to a culture obtained from the harvesting,
- and the probiotic bacteria comprises Bifidobacterium.
A probiotic bacteria comprising the galCDEGR(A) operon, the probiotic bacteria obtained by a process comprising
- fermenting the probiotic bacteria in a bacterial growth medium comprising galacto-oligosaccharides, peptone, and at least one of 3′-sialyllactose or 6′-sialyllactose;
- harvesting the fermented probiotic bacteria, and
- adding additional galacto-oligosaccharides to a culture obtained from the harvesting,
- and the probiotic bacteria comprises Bifidobacterium.
A process for increasing a therapeutic effect of a composition comprising galactooligosaccharides and a probiotic bacteria comprising the galCDEGR(A) operon, the process comprising:
- fermenting the probiotic bacteria in a bacterial growth medium comprising galacto-oligosaccharides, peptone, and at least one of 3′-sialyllactose or 6′-sialyllactose;
- harvesting the fermented probiotic bacteria, and
- adding additional galacto-oligosaccharides to a culture obtained from the harvesting,
- before incorporating the probiotic bacteria into the composition,
- and the probiotic bacteria comprises Bifidobacterium.
