【 摘 要 】

The influence of melanin-like compound "Phytocene" and surfactants on the adhesion of microorganisms was studied. "Phytocene" was obtained from buckwheat husks (Ogarkov et al., 2003). The surfaces were hydrophobized with paraffin and silicone. The experiments showed the following. Starting with a certain concentration, "Phytocene" lowered adhesion and accelerated the desorption of cells and the spores of microorganisms. Increasing the time and concentration of the suspension enhanced this effect. Similar, but more pronounced, action had typical SAS - twins. The conclusion is drawn that the surface activity of melanins can also be responsible for the biological activity of melanins.
