Abstract
Abstract An apparatus for converting into ATP which comprises an enzyme reactor, a source of AMP supply, a source of phosphoric acid donator supply, variable fluid sending apparatus, an automatic sampling apparatus and an analyzing apparatus for the reacting solution, an arithmetic control apparatus, and a recovery apparatus. According to this apparatus, conversion from AMP or ADP into ATP can be effectively carried out and ATP conversion can be kept at substantial 100% over a long period of time. The device makes it possible for ATP to be used more and more in future as an energy source for bioreactors and as medicines because the ATP will be more readily available and less expensive.
