| Outline of Final Research Achievements |
A ground level experiment was performed for space experiment. A cyanobacterium, Arthrospira platensis, was cultivated for 6 days in a device manufactured by JAXA. The amount of chlorophyll increased 9 folds, and protein increased 9 folds. It is concluded that the cell growth can be determined using this equipment. Photosynthetic activity was determined by measuring oxygen production and carbon assimilation. Stable isotopes of 18O and 13 C was used. It has been shown that growth and photosynthetic activity of the cyanobacterium can be precisely determined using this device. It seems necessary to use stable isotope in order to get reliable data.
Nanobubble water could be produced using a hand mixer by vigorous swirling. It was found that the growth of a cyanobacterium, Anabaena sp. PCC7120, was enhanced when grown in a culture medium using air-nanobubble water.
