Schematic illustration of chemical mechanisms for microalgae-material interaction. (IMAGE)
Caption
Materials combine with microalgae through intermolecular forces, covalent bond or coordinate bond, which interfere with the exchange of matter and energy between microalgae and extracellular environment. Microalgae-material interface affect photosynthetic electron transport chain through three principal pathways: (i) material hinder light energy from entering the photosystems to produce photosynthetic electrons, (ii) extracellular electrons enter the cell and involve in photosynthetic electron transport, (iii) extract electrons from the inner surface of the cell.
