为了开发海洋绿色微藻亚心形扁藻固定CO2与光产氢的一体化工艺，研究了在充气鼓泡塔生物反应器中培养的藻细胞对乙酰氰化物间氯苯肼调节光产氢的影响。当CO2浓度为3%时，细胞生长量(3.85 9×10(6)个/10(-1))、淀粉含量(0.25+/-0.08 mg/10(6)个细胞)和产氢量(50+/-3ML1(-1))均达到最高，分别是充气培养的1.4倍、2.1倍、1.5倍。H-2产量的提高与淀粉积累的增加有很好的相关性。在这个过程中，藻细胞被循环使用，在五个周期内稳定生产40-50ml L(-1)的H-2。
To develop an integrated process of CO2- fixation and H-2 photoproduction by marine green microalga Platymonas subcordiformis, the impact of algal cells grown in CO2- supplemented air bubble column bioreactor was investigated on H-2 photoproduction regulated by carbonylcyanide m- chlorophenylhrazone. Highest cell growth ( 3.85 9 10(6) cells ml(-1)), starch content ( 0.25 +/- 0.08 mg per 10(6) cells) and hydrogen production ( 50 +/- 3 ml1(-1)) were achieved at 3% CO2- supplemented culture, which are respectively 1.4, 2.1, 1.5- fold of the air-supplemented culture. Improved H-2 production correlated well with the increase in starch accumulation. In this process, the algal cells have been recycled for stable H-2 production of 40 - 50 ml l(-1) over five cycles.
