Photosynthetic organisms contribute to the circulation of oxygen or carbon dioxide and utilization of foods as a induced organism in closed bio-ecosystems. A terrestrial cyanobacterium, Nostoc sp HK-01, having a high drought tolerance, photosynthetic organism, is one of candidate organisms that can be introduced into the closed environment. It has a possibility that HK-01 has also a high gamma-ray tolerance in according to the results from several reports related to the interaction of drought tolerance and gamma-ray tolerance. Here, we will show the several influences on the growth of HK-01 after the exposure of gamma-ray in the dry colony.
