| 摘 要： | 从辐射污染的土壤中分离到一株新的耐辐射菌WGR702.该菌为革兰氏阳性球菌,直径1.5 μm～2.5μm.菌体呈粉红色、能运动、兼性厌氧及不产孢子.其生长温度和pH范围分别为10℃～35℃和pH 5.0～10.0.(G C)mol%含量为60.5%.UV和γ射线辐射检测表明WGR702具有很强的耐辐射性.16S rDNA序列(EU315117)分析表明,菌株 WGR702与沙雷氏菌属(Serratia)菌株16S rDNA序列有很高相似性(94.79%～98.53%),但与沙雷氏菌属已报道菌株最大不同点是菌株WGR702细胞为球状,且革兰氏阳性.结合形态、生理生化特征分析表明菌株WGR702可能是沙雷氏菌属(Serratia)的一个新种.
