Hydrogen production using hydrogenase-containing oxygenic photosynthetic
organisms. See esp Fig 3. "Hydrogen gas accumulation was measured with the
same setup at later times, following the onset of anaerobiosis in the sealed cultures
(Stage 2). The rate of hydrogen gas accumulation (FIG. 3, H.sub.2) was estimated to
be about 2 ml H.sub.2 h-1 (equivalent to 4.1 mmol H.sub.2 (mol Chl).sup.-1
s.sup.-1), which is less than 20% of the rate of O.sub.2 gas collected in the inverted
graduated cylinder (FIG. 3, O.sub.2)."

"For the first time, to our knowledge, significant amounts of H-2 gas were
generated, essentially from sunlight and water. Rates of H-2 production could
be sustained continuously for ca. 80 h in the light, but gradually declined thereafter."
"The rate of H2 production was fairly constant at 2.5 ml h 1 during the 27–60 h
period. This is the equivalent of ca. 5 mmol H2 (mol Chl) 1 s 1, ..."
If you don't have journal access, you can get Melis' contact info from the web
page and ask him for reprints or PDFs.
