| Abstract: | The pH changes in the blue-green alga (cyanobacterium) Anabaenacylindrica caused by addition of ammonia were investigated using31P NMR spectroscopy. A pH shift of 0.9 or more was observedwhen 30 nM NH4OH was added to the cell suspension, but no significantcellular pH change was observed with 50 mM NH4CI, a concentrationhigh enough to stimulate dark CO2 fixation of this alga. Thechange in cellular pH does not seem to cause ammonia-inducedstimulation of dark CO2 fixation. (Received June 22, 1985; Accepted January 10, 1986) |
