Chlamydomonas reinhardii cells, after a period of dark anaerobic adaptation, evolve H(2) not only in the dark but also in the light. Our results show that high irradiances impair prolonged H(2) evolution, while under low irradiances or darkness H(2) evolution proceeds for more than 50 hours. NO(3) (-) and NO(2) (-) suppress H(2) evolution both in the dark or under low irradiance. Apparently the cells prefer these oxidized nitrogen sources to protons as electron acceptors, since both NO(3… CONTINUE READING
