title: [Electrical properties and interaction with silicon dioxide particles of Bacillus subtilis cells].
abstract: It was shown that, depending on the quantity of phosphate in cultivation media, the surface layer of the Bacillus subtilis cell wall can mainly consist of either teichoic or teichuronic acids. It was found that the addition of silicon dioxide particles to the bacterial suspension induces an increase in the negative charge of the cell. This cell response to contact interaction with solid particles is observed in bacteria whose surface components are teichoic acids.
