“…As a fluence-dependent increase in dye uptake would be expected to produce a threshold for inactivation, absence of a shoulder militates against increased dye uptake being the cause of the great increase in sensitivity observed. Although membrane damage by near-UV and visible radiation has been reported for Sensitivity of E. coli to far UV, E. coli (Hollaender, 1943) and Sarcina lutea Sistrom, 1959, 1960), results reported here demonstrate that such membrane damage is an unlikely candidate for the cause of near-UV lethal effects in E. coli in the presence or absence of acriflavine or quinacrine.…”

“…This observation is consistent with previous results, suggesting the inactivating lesions induced by NUV and FUV are dissimilar (Tuveson and Jonas, 1979;Tuveson, 1980). Hollaender (1943) reported that LH (in saline) of NUV-treated cells resulted in a decline in cell viability, while Eisenstark (1971) found no effect of LH on NUV-treated E. coli cells. Peak (1970) reported that NUV-treated E. coli cells exhibited LHR.…”

“…When NUV-treated cells are held at relatively high densities (108-109 cells/m/), damaged cells may lyse releasing nutrients which allow growth of undamaged survivors in non-nutrient suspending medium. At relatively low cell densities (perhaps 5 x 10' cells/m/ or less as used by Hollaender, 1943), damaged cells may not release sufficient nutrients to allow significant multiplication of undamaged survivors.…”

“…The deleterious effects of near-W and visible light such as growth delay, mutagenesis, carcinogenesis and lethality (Pollard, 1974;Hollaender, 1943) is amenable to repair in bacterial and animal cells (Ramabhadran and Jagger, 1974; Webb and Lorentz, 1970; Chatterjee and Bhattacharjee, 1975). In bacteria, recombination is involved in the repair of damage induced by these radiations (Eisenstark, 1970;Gopalakrishna and Bhattacharjee, 1976).…”
