Outline of Final Research Achievements

Aspergillus oryzae is known as an important microorganism utilized as koji mold in fermentation food industry. In this study, the amount of polyphosphate was examined under several culture condition, and found that some effects were observed under the stress of metal ions, oxidation etc. Especially, polyphosphate was found to increase in response to some stress conditions. From these studies, new information concerning on polyphosphate was obtained, which was not known among filamentous fungi.
