Role of the clasping-leaved pondweed (Potamogeton perfoliatus) polysaccharides in formation of its bacterial environment

摘要

The effect of the polysaccharides of clasping-leaved pondweed (Potamogeton perfoliatus) on the formation of a bacteriocenosis of this plant was demonstrated by research on chemoreception, relative surface hydrophobicity, and the growth characteristics of the members of five bacterial genera abundant in this micro biocenosis. The plant heteropolysaccharides of anionic and cationic nature were found to participate in selective stimulation or inhibition of growth of some microbial groups in surrounding water. These findings improve our understanding of the spectrum of physiological activity of glycopolymers of diverse origin.
