‘Restoration’ of Escherichia coli strain B After Irradiation: its Dependence on Suboptimal Growth Conditions

摘要: SUMMARY: After irradiation of Escherichia coli strain B by ultraviolet or ionizing radiations, different plating media give rise to widely viable counts; the surviving fractions are smallest on which optimal for growth unirradiated organisms. It is concluded that inhibition colony formation after due in part an injury leads imbalance synthetic processes cell, so ‘recovery’ ‘restoration’ may be brought about suboptimal conditions growth. The proportion cell deaths ascribed this particular determined obtaining bacterial suspensions before and during irradiation, also type radiation used.
