Abstract
Spectra of photoluminescence of bacterial suspension of different concentrations and DNA suspension are represented in given paper. The photoluminescence was excited by laser UV radiation. The investigated microorganisms were in a spore condition. The luminescent spectra, excited by the radiation of different intensities were recorded. Evolution of photoluminescent spectra in dependence on changing of bacterial suspension's concentration and delay time of a strobe-pulse of registration system was defined. We have also established that the photoluminescent spectra of investigated samples were situated in a near-UV-blue spectral region. Difference of photoluminescent spectra of bacterial samples that were preliminarily irradiated by tough UV light and so absorbed different doses of UV energy from spectra of non-irradiated bacterial samples was notices. Kinetics of luminescent level during the irradiation by laser UV light was investigated.
