title: [The effect of the acidity of the medium on the magnitude of the light-dependent antibacterial activity of chlorophyllides].
abstract: The influence of medium acidity on the intensity of light-dependent antibacterial activity of chlorophyllides isolated from biomass of microscopic green alga Westella botryoides has been studied. This light-dependent antibacterial activity has been shown to be maximum at low pH values. The ability to suppress the bacterial growth under the action of light decreases in neutral and alkaline media. It has been concluded that the reason of increase of light-dependent antibacterial activity of chlorophyllides at low pH values is formation of pheophorbides out of them
