1. A process for producing a dry, storage-stable preparation, containing revitalizable bacteria, in the form of a powder or granules by spraying a cell suspension of at least one strain of bacteria onto an excipient composition, in the form of a powder or granules suspended as a fluidized bed, drying the sprayed excipient composition in the fluidized bed by means of a hot gas, and packaging the preparation of bacteria under an oxygen-free protective gas, characterized in that - a cell suspension of the strain Lactobacillus brevis DSM 2647 or a mixture of this strain with strains of other bacteria is sprayed onto coarse cereal metal and/or cereal flour as the excipient composition, and - the sprayed excipient composition is dried at a temperature of 20 to 90 degrees C by means of hot air to a content of 60 to 95 % by weight of dry matter, resulting in a preparation of bacteria containing at least 10**9 cells per gram which are viable after rehydration, and which is free of physiologically or pharmacologically unacceptable additives. |
