Flocculation of C. protothecoides and T. suecica by 15 fungal strains. (A) 12-well microtitre plate experiment: fungal pellets were mixed with suspensions of C. protothecoides (left wells) and T. suecica (right wells) for 24 h. Controls: microalgal suspensions grown without fungi (top wells); fungal cultures grown alone (middle wells). (B) Flocculation efficiency measured by reduction in optical densities, cell numbers and chlorophyll concentrations of uncaptured algal cells after 24 h of co-cultivation.
