Eighteen survivor strains of Bacillus pumilus E601 have been isolated after single sublethal irradiation treatments with 60Co. Primary isolation was based on the loss of motility and pellicle formation. However, with subsequent subcultivation, eight isolates reverted back to the standard of exhibiting motility and pellicle formation. Characteristics of the isolates include alterations in space radiation resistance and in the amino acid requirements for spore germination and outgrowth. Other alterations in cultural and physiological characteristics were found. Three of the isolates were asporogenous.
在用60Co进行单次亚致死剂量辐照处理后，已分离出18株短小芽孢杆菌E601的存活菌株。初次分离基于运动性丧失和菌膜形成情况。然而，在随后的传代培养中，有8株分离株恢复到表现出运动性和菌膜形成的标准状态。这些分离株的特征包括空间辐射抗性以及孢子萌发和生长的氨基酸需求方面的改变。还发现了培养和生理特征的其他改变。其中3株分离株不产芽孢。
