Beschreibungen/Notizen

• While investigating the effects of silicon limitation on the diatom Nitzschia cf. pusilla, we observed, along with expected lower maximum cell density, colony formation. Cells attached in stacks that increased in number, reaching an average of 30 ± 1.8 (mean ± SE) cells per stack. Cells grown under silicon-replete conditions formed short stacks (three to four cells) in the stationary phase. When silicon-depleted cultures were split and silicate was added to half of the split cultures, cell stacks decreased in the cultures to which silicate was added. These results suggest that N. pusilla may possess an adaptive strategy to survive and maintain growth under silicon limitation.
