title: Simplified fluctuation test to distinguish liquid holding recovery from cell multiplication in ultraviolet-irradiated Escherichia coli.
abstract: Improved plating techniques and a fluctuation test have been used to distinguish between liquid holding recovery of ultraviolet-irradiated cells and cell multiplication in Escherichia coli. Among tested strains, only recA mutants showed true recovery.
