The well known radiation-resistance bacterium Deinococcus radiodurans and Escherichia coli X1488 and non-cellular ATP were used for X-ray irradiation. On the other hand, Deinococcus radiodurans and two spore-forming bacterium Virgibacillus and four strains of Escherichia coli (each strain of Escherichia coli have another radiation-sensibility) were used for Fe ion irradiation. The results of X-ray irradiation were: (1) Cellular ATP showed highest survivability in the D.radiodurans and celluar ATP decreased exponentially. Whether non-celluer ATP did proportionally. (2) D.radiodurans survived extremely high-dose of X-ray. The lethal dose was several thousands greater than that of E.coli. The results of Fe ions radiation were (1) Cellular ATP decreased exponentially but only D.radiodurans's did proportionally. (2) CFU of E.coli and D.radiodurans showed rapid decrease at the dose of over 50 Gy. However, only D.radiodurans survived at the dose of 2000 Gy. These results suggest that (1) Irradiation of X-ray and Fe causes another effect on microbial cells. Fe ions showed greater effect on microbial cells than X-ray. (2) Each bacterium has their characteristic radiation resistance such as DNA repair capability or spore forming. More different radiation type and more bacteria strains should be used in future study.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
