摘要
四爿藻 (Tetraselmissp.)、微绿球藻 (Nannochloropsisocculata)、小球藻 (Chlorellavulgaris)和扁藻 (Platymonassubcordiformis)的放氢特点各不相同。在暗厌氧培养阶段 ,四爿藻和微绿球藻不释放氢气 ,小球藻和扁藻释放微量的氢气。随后的光照培养阶段中 ,4种海藻在天然海水中都释放氢气 ,四爿藻和小球藻在无硫海水中不释放氢气 ,而微绿球藻在无硫海水中释放的氢气比在天然海水中的少 ,扁藻在无硫海水中释放的氢气为天然海水中的10倍。在4种藻中 ,亚心型扁藻的光合放氢能力最高。解偶联剂CCCP(carbonylcyanidem -chlorophenylhydrazone)对该4种藻的光合放氢的影响各不相同 。
The characters of hydrogen evolution by Tetraselmis sp., Nannochloropsis occulata, Chlorella vulgaris and Platymonas subcordiformis are distinct. In dark and anaerobic stage, no hydrogen was evolved by Tetraselmis sp. and Nannochloropsis occulata, and tiny amount of hydrogen was evolved by Chlorella vulgaris and Platymonas subcordiformis. In photo-hydrogen production stage, all of the four algal strains evolved hydrogen in natural seawater. No hydrogen was evolved by Tetraselmis sp. and Chlorella vulgaris in sulfur-deficiency seawater, less hydrogen was evolved by Nannochloropsis occulata in sulfur-deficiency seawater than that of in natural seawater About ten-folds of hydrogen was evolved by Platymonas subcordiformis in sulfur-deficiency seawater than that of in natural seawater. There are different effects on photo-hydrogen production by uncoupler CCCP(carbonyl cyanide m-chlorophenylhydrazone)in the four algae and the possible limiting step was suggested.
