Abstract
Near-ultraviolet radiation (300 to 380 nm) induces a transient growth inhibition in "stringent" (rel+) strains of Escherichia coli, whereas "relaxed" (rel-) strains are only mildly affected. This difference permits rapid isolation of large numbers of relaxed mutants of E. coli.
摘要
近紫外辐射（300至380纳米）会在大肠杆菌的“严谨型”（rel+）菌株中诱导短暂的生长抑制，而“松弛型”（rel-）菌株仅受到轻微影响。这种差异使得能够快速分离出大量大肠杆菌的松弛型突变体。
