Abstract
Vela, Gerard R. (School of Aerospace Medicine, Brooks Air Force Base, Tex.), and Orville Wyss. Radiation resistance of soil Azotobacter. J. Bacteriol. 89:1280-1285. 1965.-Quantitative recovery of Azotobacter from soils subjected to gamma-radiation from a cobalt-60 source showed the soil populations to be much more highly resistant than isolates from such cultures grown on laboratory media. Even in the encysted state, the laboratory populations were reduced 10,000-fold by exposure to 200 kr, whereas the soil populations were not measurably reduced by that dose.

韦拉，杰勒德·R.（德克萨斯州布鲁克斯空军基地航天医学学院）以及奥维尔·怀斯。土壤固氮菌的辐射抗性。《细菌学杂志》89:1280 - 1285。1965年。 - 对来自受钴 - 60源γ辐射土壤的固氮菌进行定量回收显示，土壤菌群的抗性比在实验室培养基上培养的此类菌株的分离物高得多。即使处于孢囊状态，实验室菌群经200千伦琴照射后数量减少了10000倍，而该剂量对土壤菌群数量没有可测量的减少。
