Additional file 8: Figure S7. Bio-flocculation of different microalgal strains by BAPS-52-1, BAPS-52-2, and BAPS-52-1 + BAPS-52-2. (A–D) Isochrysis sp. cells co-cultured with a mixture of BAPS-52-1 + BAPS-52-2; (E–J) Isochrysis sp. cells co-cultured with BAPS-52-1; (G–J) Isochrysis sp. cells attached to the biofilm produced by BAPS-52-1 attached to the microscopic slide; (K–N) N. oculata cells co-cultured with a mixture of BAPS-52-1 + BAPS-52-2; (O) Nannochloris sp. cells co-cultured with a mixture of BAPS-52-1 + BAPS-52-2; (P) Nannochloris sp. cells co-cultured with BAPS-52-2 filaments. (C, F, H, J, N) Images under UV light. Scale bars represent: (A–L, N–P), 50 µm; (M), 20 µm
