Figure 3
SEM images of the sponges under different treatments (PBCA, sponges in the PBC system without cleaning; PBCF, sponges in the PBC system with cleaning; PBOA, sponges in the PBO system without cleaning; PBOF, sponges in the PBO system with cleaning). Images in the same column are the same sample at different magnifications; images in the first (a), second (b), and third (c) lines are magnified 100 times, 10,000 times, and 20,000 times, respectively. Note. C. pyrenoidosa is circled in B and C in PBCA.
