FIGURE 7. Results of plate assay (A) and zymographic analysis (B) for cellulase activity of Polydora tunicola sp. nov. Haloes (A: destained areas) and destained bands (B: arrowheads) indicate the cellulose decomposition (exhibition of cellulase activity). PC = positive control (crystalline style of a brackish water clam Corbicula japonica), NC = negative control.
