内容記述(抄録等)Ishikurage is the jelly aggregate formed by desiccation-tolerant cyanobacteria, Nostoc sp. In the present study, we examined the persistence of the viability of Ishikurage in response to physical and chemical stresses that would arise in the process of manufacturing to materials for reforestation. Wet Ishikurage lost its photosynthetic activity during storage under dark conditions. Growth of Ishikurage was delayed under low temperature conditions, while the photosynthetic activity was not affected. Photosynthesis was maintained when Ishikurage was soaked in buffer solutions adjusted between pH3 to 9. When wet Ishikurage was strongly homogenized, the photosynthetic activity decreased. During the rewetting process, the activity did not differ among fractions of several sizes prepared by homogenization and sieving of air-dried Ishikurage. Except for the size fraction smaller than 1 mm, Ishikurage placed on soil surface inhibited desiccation of the underlying soil. These findings could provide major data for manufacturing processes.
