Removal of raffinose and stachyose from soy

In this Workpackage, the research focus was on isolation and/or construction of strains with high Ą-galactosidase activity. Partner 05 was responsible for the targeted expression of a-galactosidase (encoded by the melA gene) in Lactococcus lactis, Partner 06 looked for sources of enzymes with high a-galactosidase activity and performed all the animal trials and Partner 07 screened their culture collection for lactic acid bacteria with high Ą-galactosidase activities. This partner also supplied the soy material that can be pre-fermented for a-galactoside-removal.
Newly isolated and constructed strains have been used successfully in animal experiments to test for raffinose and stachyose removal leading to reduced flatulence (gas formation).
