The invention relates to a cell immobilising carrier, which can be used in a novel continuous fermentation process. More particularly, this fermentation process is used in the continuous production of beer. The immobilising carrier comprises a porous medium of fibers. The medium has a porosity of at least 70 %.

The invention relates to a method for the continuous biocatalytic conversion of aqueous solutions containing biocatalytically convertible material in a reactor, having one or more converting/degassing stages in parallel or serial interconnection, each converting/degassing stage comprising a bioreactor and a degassing device in serial interconnection, where in each converting/degassing stage in a first process step an aqueous solution containing biocatalytically convertible material is fed in continuous flow to the inlet of the bioreactor where it is contacted with a biocatalyst, and where in a second process step the biocatalytically converted solution is transferred from an outlet of the bioreactor to an inlet of the degassing device, and at least part of the degassed solution leaving the outlet of the last degassing device in line is fed to the inlet of the first bioreactor in line in a continuous flow. The invention further relates to an apparatus for carrying out such a method.

摘要:
The object of the present invention is to provide a fermentation product excellent in flavoring quality by a method in which the fermentation time can be reduced and the long-term operation is feasible in producing the fermentation product such as alcoholic beverages in the fluidized-bed reactor. The present invention relates to a process for producing a fermentation product wherein an immobilized microorganism is arranged in a fluidized bed reactor provided with a fluidized bed part, a liquid circulating part and a gas exhaust part, and a raw-material solution is fed to the reactor to conduct fermentation, characterized in that a part of a fermented solution is drawn out from the fluidized bed part and the fermented solution is returned again to the reactor whereby a fluidized bed is formed while fermentation is conducted, and the fermentation product is put out from the reactor while new raw-material solution is fed to the reactor so that the above fermentation is repeatedly carried out.
