(A) Flocculation of C. protothecoides: A. fumigatus culture (left); mixotrophically grown C. protothecoides culture (middle); A. fumigatus/C. protothecoides pellets (right). (B) Flocculation of T. suecica: autotrophically grown T. suecica culture (left); A. fumigatus/T. suecica pellets (right). (C) T. suecica culture mixed with A. fumigatus pellets, time = 0 (left); 24 h later (right). (D, E) A. fumugatus pellets grown PDB (left) and 1% TWS (right). (F) Flocculation of T. suecica: A. fumigatus/PDB-T. suecica pellets (left); original T. suecica culture (middle); A. fumigatus/TWS-T. suecica pellets (right).
