Hydrogenase Activity in Scenedesmus D3 Cultured in a Medium Containing Carrot Extract1

Hydrogen evolution in relation to PS I-reducible substrates in the cyanobacterium Oscillatoria chalybea assayed by means of mass spectrometry

“…Also, nitrite inhibited glucose fermentation in ammonia grown E. coli; cytochrome e-552 may be involved in both nitrite reduction and fermentation [26]. Earlier, nitrite as a hydrogen acceptor in cells of Scenedesmus has been used [27].…”

Correlation between respiration and hydrogenase adaptation in Scenedesmus obliquus

“…According to a number of workers (Gaffron and Rubin 1942, Gingras et al 1963, Hartmann and Krasna 1962 the hydrogenase of Scenedesmus exhibits its activity only after a dark period in the absence of O,. However, it was also reported that in media containing boiled carrot extracts, cells of Scenedesmus (Chiba andSasaki 1963, Stiller andLee 1964) and Chlorella (Stiller and Lee 1964) develop active hydrogenase without dark anaerobic adaptation. This effect was enhanced by glucose, indicating a possible correlation between respiration and hydrogenase adaptation.…”
