title: [Effect of tririum on growth and bioluminescence of P. phosphoreum bacteria].
abstract: Effect of tritium labeled amino acid valine (0.3-1.0 MBq/ml) on luminous bacteria P. Phosphoreum was studied. The amino acid was used as a nutrient medium for the bacteria. Tritium was found to suppress bacterial growth, but stimulate luminescence: luminescence intensity, quantum yield and time of light-emitting were increased. Activation of the luminescent function is explained by redistribution of electronic density at beta-decay, and affecting biochemical processes in the bacterial media. Effects of alpha- and beta-radiation on luminous bacteria are compared.
