title: [Effect of perfluorodecalin, carbogal, and perfluoromethyldecalin on growth and ice-forming activity of bacteria].
abstract: The isolates of pseudomonads (56) and of Plesiomonas shigelloides (7) exhibiting ice-forming activity were isolated from plant leaves and rhizosphere. The theoretical possibility of the application of perfluorocarbons (PFC) with a gas-transporting function (perfluorodecalin, carbogal, and perfluoromethyldecalin) for the cultivation of bacteria with different levels of ice-forming activity (IFA) in order to enhance their growth rates, biomass yields, and IFA was demonstrated. Introduction of 5% perfluorodecalin, carbogal, or perfluoromethyldecalin resulted for two strains in a 1.7-3.1-fold increase in biomass and a 3.2-24.5-fold increase in ice-forming activity compared to the control (without PFC).
