Slow transients of light-induced pH changes at the outer surface of photosynthetic membranes
Acta botanica neerlandica , Volume 26 - Issue 1 p. 89- 93
Non-artificial transients, with a halftime of about 10 sec., of light-induced pH changes occur in fresh suspensions of spinach chloroplast fragments. The transients were observed with rapid direct pH measurements as well as the fluorescent probe technique. Ageing of the preparations for 2-3 hrs. at room temperature annihilates the transients, whereas photoinduced pH changes still occur.
