✦ Synopsis

A synchronized akinete differentiation occurred within 3 days when Nodularia filaments were incubated at a higher temperature (32 1 "C). Exogenous nitrogen and carbon compounds increased the akinete frequency. The cyanophycin content of akinetes was found to be nearly 6 times higher than that of exponentially growing vegetative cells. The results suggest that the akinete differentiation is induced by the rise in temperature and akinete frequency is regulated by cellular carbon and nitrogen levels.
