Structural Features of the Algal Cell Determine Adhesion Behavior at a Charged Interface

Abstract We aimed to examine the effects of algal structural features on adhesion at a charged interface. Results showed that algae with a glycocalyx, and with a cellulose amphiesma adhered at a charged interface at species‐specific potential ranges. Algae, encased with a calcite‐encrusted theca, and with an organosilicate cell wall, did not adhere to the interface. These differences in the amperometrically determined adhesion behavior of algal cells are in agreement with reported cell mechanical properties. Critical interfacial tensions of adhesion show differences between the studied soft algal cells as a consequence of their distinct cell barrier structure, composition, and properties.
