Feasibility of Marine Microalgae Immobilization in Alginate Bead for Marine Water Treatment: Bead Stability, Cell Growth, and Ammonia Removal

Figure 2

The diameter (mm) of alginate bead during initial and final incubation periods. The different letter at each initial and final period indicated significant difference ( value ≤ 0.05) between alginate beads prepared by using different (a) alginate concentrations and (b) hardening by different concentrations of CaCl₂ solution. The different number at each treatment indicated that initial size of alginate bead is significantly different ( value ≤ 0.05) from final size of bead.
