Abstract:
1. A system for estimating survival cell count which estimates a survival cell count of a specific strain contained in a solid composition after storage, the composition being sealed in a moisture barrier container, the system comprising: a plural number of moisture barrier containers configured so that specific strain-containing solid composition samples can be individually packed and sealed up therein; a storage device which can maintain a fixed storage temperature (° C.); and a device which comprises: an input receiver which receives an input of information on conditions for calculating the survival cell count, which presents a storage period of the composition containing said strain, a viable cell count of said strain contained in said composition at the initiation of storage, a storage temperature of said composition, and a water activity value of said composition; a calculation unit which calculates the survival cell count of said strain contained in said composition after said storage period, by substituting the storage period of the composition containing said strain, the viable cell count of said strain contained in said composition at the initiation of storage, the storage temperature of said composition, and the water activity value of said composition, presented by said information on conditions for calculating the survival cell count, input of which has been received by said input receiver, into the following equation (I); and an output instruction unit which instructs to output information indicating the survival cell count of said strain contained in said composition after said storage period, which has been calculated by said calculation unit, t: storage period (days)× 1/30 n n T: storage temperature (° C.) w: water activity value of the composition A B C D
