Estimating the term…
The present invention relates to a method for immobilising microorganisms (particularly yeasts or bacteria), a related material, and the use thereof in fermentation or bioconversion. Specifically, the present invention relates to the immobilisation of microorganisms in optionally dehydrated polymeric spheres consisting of two or more layers. The technical problem is that only part of the total microorganism population, namely the microorganisms adjacent to the edge of the sphere, is actually active in conventional spheres. According to the present invention, this problem is solved by providing a nutrient supply in the center of the sphere and placing the microorganisms in a layer adjacent thereto, the resulting combination optionally being coated with a sterile layer defining, in this embodiment, a triple-layer sphere.
Method for immobilizing microorganisms characterized in that an adequate nutrient supply for said microorganisms is incorporated into a medium for the fixation of the microorganisms and crosslinking of this support medium is carried out.
Product with immobilized microorganisms characterized in that it includes a nutrient supply incorporated in the fixation medium of the microorganisms.
