The present invention includes compositions and methods for making and using an isolated cyanobacterium that includes a portion of an exogenous bacterial cellulose operon sufficient to express bacterial cellulose, whereby the cyanobacterium produces extracellular glucose. These capsules have been found to be sensitive to the presence of base such that in the presence of base, the capsule walls are relatively quickly disintegrated or degraded so as to produce a relatively quick release of the encapsulated materials. The server apparatus, when receiving purchase information, which consists of personal information of a purchaser of a commodity and the sales information that is presented to the purchaser by a seller of the commodity, judges whether the sales information included in the received purchase information is stored in the first storing part.
