Abstract
The hyphae of Gaeumannomyces graminis and the cells of some antagonistic bacteria adsorb clays and this may affect the ability of the antagonists to lyse the hyphae. The use of frozen hydrated specimens for scanning electron microscopy shows that some sand, plant root, and microbial surfaces are not covered with mucilage and water films. Hyphae especially may pass through liquid–gas interfaces very frequently and their surfaces may pass from being a solid–liquid interface to a solid–gas interface over very short distances. The effect of these changing interfaces on adsorption of clay and bacteria is discussed.
