Studies on the causes of biological activity of water bacteria Aeromonas and Pseudomonas genus

Abstract

Investigated the factors responsible for antagonistic and stimulating activity of the selected bacteria strains of Aeromonas and Pseudomonas genus. By application of paper chromatography method and gel separation on Sephadex column, obtained several fractions of bacterial culture examined extracts. Determinations were made on the biological activity of fractions and on the presence in them of proteins, lipids and polysaccharides.
