Heavy metal accumulation results, from field

In addition to the field experiments, the Cd uptake by F. antipyretica was tested under laboratory conditions. Concentrations of 1.12 mg/100 ml were added to the culture medium (Knop medium, modified) and the accumulation monitored over 10 days. The results are presented in Table 14. The data confirm that F. antipyretica accumulates heavy metals like Cd to a large extent. The enrichment is a time-dependent process, starting with a fast equilibration followed by several days of slower Cd uptake. There is a slow increase of the intracellular Cd content, which is a result of migration from extracellular binding sites into the cell.
