Item Utilization of the terrestrial cyanobacteria(44th International Conference on Environmental Systems, 2014-07-13) Katoh, Hiroshi; Yokoshima, Mika; Kimura, Shunta; Furukawa, Jun; Tomita-Yokotani, Kaori; Yamaguchi, Yuji; Takenaka, HiroyukiThe terrestrial, N2-fixing cyanobacterium, Nostoc commune has expected to utilize for agriculture, food and terraforming cause of its extracellular polysaccharide, desiccation tolerance and nitrogen fixation. Previously, the first author indicated that desiccation related genes were analyzed and the suggested that the genes were related to nitrogen fixation and metabolisms. In this report, we suggest possibility of space-agriculture, using the cyanobacterium. To estimate space-agriculture, we need to discuss the features of cyanobacteria, especially terrestrial cyanobacteria and the utilization. Further, we also found radioactive compounds accumulated N. commune (cyanobacterium) in Fukushima, Japan after nuclear disaster. Thus, it is investigated to decontaminate radioactive compounds from the surface soil by the cyanobacterium and showed to accumulate radioactive compounds using the cyanobacterium. We will discuss utilization of terrestrial cyanobacteria under closed environment.Item Utilization of the terrestrial cyanobacteria -Practical development of the cyanobacteria sheet-(46th International Conference on Environmental Systems, 2016-07-10) Katoh, Hiroshi; Yokoshima, Mika; Kimura, Shunta; Furukawa, Jun; Tomita-Yokotani, Kaori; Yamaguchi, Yuji; Takenaka, Hiroyuki; Kohno, NobuyukiThe terrestrial, N2-fixing cyanobacterium, Nostoc commune has expected to utilize for agriculture, food and terraforming cause of its extracellular polysaccharide, desiccation tolerance and nitrogen fixation. Potential abilities of N. commune were shown previously (Katoh et al. 44th ICES, 2014). To exhibit the potential abilities, the N. commune sheet is made to use convenient and evaluated by plant growth and radioactive accumulation. We will discuss utilization of terrestrial cyanobacteria under closed environment.
