含量对扁藻生长及光合放氢均有影响
其中φ(CO

)为3%时培养及光合放氢的效果最好
培养的藻细胞10 d细胞密度倍增3.8倍

在15 μmol/L解偶联剂羰基氰化物间氯苯腙(CCCP)作用下连续光照24 h
培养的藻细胞产氢量提高70%
最大比产氢速率为3.24 mmol/(g·h).代谢分析表明
φ(CO

The kinetics of cell growth and photohydrogen evolution of P. subcordiformis grown under CO
2
-supplemented air bubble bioreactor is investigated. The highest cell growth was achieved as φ(CO
2
)got to 3%
and was supplemented to the air
with a specific growth rate of 0.134 d

. The hydrogen photoproduction was enhanced by 70% for cells grown under 3% of φ(CO

)
with a specific hydrogen production rate of 3.24 mmol/(g·h)

. The metabolic analysis of algal cells indicated a significant increase in starch accumu
lation with the increasing CO
2
concentrations. The highest starch content was achieved under 3% of φ(CO
2
)supplemented alga cells
2.1 times the control culture in air. The improved hydrogen production may correlate with the increased starch accumulation where CO
2
serves as the sole carbon source. These results suggest that hydrogen photoproduction by marine green alga can be beneficial from CO

-supplemented cultivation
which exerts a positive impact on the greenhouse gas mitigation.
