Isolation of an E. Coli B Strain Resistant to Sonic Disintegration

摘要

A strain of E. coli Bsg surviving intermittent short bursts of lysing ensonification during mitotic cycling exhibits a profound resistance to a 15-minute continuous sonification exposure. This level of resistance was noticed in the second and succeeding generations of survivors. In contrast, E. coli B survivors from direct exposure to 15-minutes of lysing ensonfication evidence no heritable resistance. Reasons for these differences are discussed. (Author)
