抄録

A dense suspension of Spirulina platensis trichomes aggregated rapidly and formed a disk-shaped algal mat when cAMP was added. Cyclic AMP significantly stimulated algal mat formation at concentration as low as 10^<-7> M. Stimulation of the mat formation was most rapid at about 10^<-5> M cAMP, but higher concentrations were not increasingly effective. Other nucleotides such as cGMP, ATP and AMP showed no stimulatory effect on algal mat formation. CCCP, an inhibitor of ATP synthesis, was found to suppress the cAMP-stimulated algal mat formation. Cyclic AMP also stimulated respiration and gliding movement of this cyanobacterium.
