- 論文の詳細を見る
The presence of NaCl was essential for cAMP-induced cell aggregation leading to a mat formation in the cyanobacterium Spirulina platensis. The most effective concentration for the mat formation was 0.25 M and higher concentrations were inhibitory. The mat formation occurred under a physiological pH of 7 to 9. Li^+ and K^+ were less effective than Na^+ and divalent cations such as Ca^<2+> or Mg^<2+> showed no effect on the mat formation. It was suggested that Na^+ enabled the mat formation by supplying energy to cells for aggregation.
