Abstract Light‐induced proton efflux has been investigated with intact cells of Anabaena, Nostoc, Anacystis , and Aphanocapsa . The proton efflux by filamentous blue‐green algae is biphasic, strongly inhibited by ortho ‐vanadate and insensitive to cyanide. These data are taken as evidence for a proton‐pumping ATP‐hydrolase present on the cytoplasmic membrane of Anabaena and Nostoc .
