The effect of pH on A. subfuscus glue mechanical properties and ion content. (a) The elastic modulus after soaking for 5 min in different acetate buffers. Data shows mean ± s.e.m. (N = 6 for each pH value). (b) Time course of magnesium diffusion from the glue at neutral and acidic pH. (c) The amount of calcium removed from the glue in 1 h of soaking in acetate buffers of different pH. (d) The amount of magnesium removed from the glue in 1 h of soaking in acetate buffers of different pH. All ion content values are given as a percentage of the starting concentration, which was measured after 1 h incubation in 0.7% nitric acid (1901 ± 132 ppm calcium, 593 ± 88 ppm magnesium).
