Figure 2 in Germanium dioxide as agent to control the biofouling diatom Fragilariopsis oceanica for the cultivation of Ulva fenestrata (Chlorophyta)

Figure 2: Total diatom biomass at different GeO2 concentrations after 22 days of cultivation at 137 µmol photons m−2 s−1 and 9 °C. Data are means of three replicates per treatment (n = 3) and error bars represent standard deviations. Lowercase letters above columns indicate statistically significant differences between the treatments (P <0.001, 1-way ANOVA, Tukey-Kramer HSD post-hoc test).
