ZINC-ENRICHED BIOMASS, METHOD FOR THE PREPARATION THEREOF AND PRO-BIOTIC, COSMETIC, DIETARY AND NUTRACEUTIC PRODUCTS COMPRISING THE SAME

摘要

The invention relates to a zinc-enriched biomass comprising living or subsequently killed micro-organisms, selected from the group consisting of Streptococcus thermophilus and Bifidobacterium animalis subsp. lactis and combinations thereof, a method for the manufacture of said zinc-enriched biomass, as well as food preparations, nutraceutic products, functional foods, cosmetic and cosmeceutic products, and food supplements, comprising the said biomass. Furthermore, new micro-organism strains are described which are able to concentrate zinc within the cell in very high amounts and therefore are particularly suitable for use in the method of the invention.

主权项

1. A zinc-enriched biomass, obtainable by a method comprising:
(i) culturing micro-organisms selected from the group consisting of Bifidobacterium animalis, Streptococcus thermophilus, and combinations thereof, in a nutrient culture medium comprising a zinc salt in a concentration between 5 to 50 mM, to obtain zinc-enriched micro-organisms so that said micro organisms accumulate zinc; and (ii) separating the zinc-enriched micro-organisms from the culture medium.
