Results/More Information

Of the lyophilically dried bacteriophages exposed on the ISS one, Staphylococcus aureus bacteriophage exhibited increased lytic activity. Data indicated that in the lyophilically dried forms of bacteriophages exposed to space factors, the structure of particles was unchanged and the heads of the phage particles contain DNA. The biological properties of the bacteriophages (morphology of negative colonies, spectrum of lytic action, and stability under the influence of fluctuating pH levels) do not change relative to initial data. All studied bacteriophages retained their viability and biological activity after being in space for 3 months. However, it was noted that the concentration of bacteriophages was an order of magnitude lower than the initial concentration.
