The aim of this review was to present the results of more than ten-year study of gaupsin biopreparation created on the basis of two strains Pseudomonas chlororaphis subsp. aureofaciens UCM В-111 and UCM В-306 with antifungal, entomopathogenic and antiviral activities. Data about antibiotic substances produced by these strains — phenazine and phenylpyrrole derivatives — are presented. Entomocidal properties against the wide spectrum of insect pests have been found out in the strains-producers. Antiviral activity of gaupsin due to the production of thermostable exopolymers containing neutral monosaccharides has been shown using the tobacco mosaic virus as a model. Lipopolysaccharides of the strains В-111 and В-306 also appeared to be highly active antiviral agents. Structure of their O-specific polysaccharides has been established. The last one are structurally heterogenic, presented by linear tri-and tetrasaccharide repeated links and have specific structure that has not been described previously.

Key words: gaupsin biopreparation, Pseudomonas chlororaphis subsp. aureofaciens, antibiotics – phenazines, pyrrolnitrine, entomopathogenic properties, antiviral activity.
