Role of photochemical processes in the reduction of nitrate by green algae

ABSTRACT EXPERIMENTS have been described supporting the idea that reduction of nitrate in the light by green algae is a photochemical process1. However, a strong argument against this

assumption is the fact that, without carbon dioxide, a really significant reduction of nitrate in the light has never been found2,3; only several hours after the addition of glucose can a

strong evolution of oxygen due to nitrate reduction be observed3. This indicates an indirect influence of light via the formation of photosynthetic products rather than a direct

photochemical reduction of nitrate. In the following we show that it is necessary to distinguish between the effect of light on the reduction of nitrate and nitrite, respectively (cf. also

Harvey's results with diatoms4). The latter is the first intermediate in the reduction of nitrate by green algae5. Access through your institution Buy or subscribe This is a preview of
