- W2050804952 abstract "Two green algae, Monoraphidium dybowskii and Stichococcus sp., were exposed to aluminium at some ecologically relevant concentrations within a pH range of 5.0–6.0. Growth experiments in batch cultures showed some difference in tolerance response between the two species. Cell decomposition was detectable at 0.10 mg All−1 but was more pronounced at higher Al concentrations. Monoraphidium showed higher tolerance to aluminium than did Stichococcus when EC50 values were considered. The growth rate of this alga was reduced to 50% of the control when it was exposed to 1 mg All−1. The EC50 value for Stichococcus was 0.52 mg All−1. Upon measurement of the 50% reduction in maximum cell biomass, about the same values (0.4 mg All−1 were noted for both algae. Calculation of the area under the growth curve gave a more integrated growth response resulting in intermediate values for both algae but still half as high for Stichococcus as for Monoraphidium. However, no effective concentration (NOEC) and least concentration significant effect (LCSE) of aluminium, were signified by lower values (around 0.02 mg l−1 for Monoraphidium compared with those (0.11–0.23 mg l−1) for Stichococcus, which responded more dramatically when the Al concentration was increased. The increase in cell number production was progressively more affected during the growth experiments. Cells of Stichococcus, however, seemed to adapt to some extent after more than 3 days of exposure, showing higher tolerance at intermediate Al concentrations after some additional days of exposure." @default.
