摘要	Water samples from various marine, freshwater and terrestrial environments in China have been collected and screened in our laboratory for wild clones of microalgae since 2008. Hundreds of microalgal clones were purified through plate streaking, of which 52 strains have been screened for their ability to produce H-2 under anaerobic conditions. Twenty eight strains including 13 freshwater green algae, 12 marine green algae and 3 cyanobacteria were found to evolve H-2 under sulfur or nitrogen deprivation. Parietochloris incisa, Chlorella protothecoides, Chlorella capsulata, Nannochloropsis sp., Tetraselmis helgolandica, Pyramimonas sp., Chlorella autotrophica, Dunaliella apiculata, Tetraselmis striata and Tetraselmis tetrathele were first reported as new H-2 producing species. Among those H-2 producing strains, freshwater C. protothecoides showed the highest H-2 producing capacity (2.93 H-2 ml/l/h) and accumulated up to 123.6 ml H-2 per liter culture under sulfur deprivation. Marine C. autotrophica and T. striata were two notable green marine species that produced H-2 phototrophically, with 3.73 ml/l and 20.11 ml/l of H-2 yield respectively. Our results also demonstrated that both the likelihood of a strain producing H-2, and the average H-2 output, in freshwater strains were much higher than that in marine strains. In addition, the time for inducing H-2 production in freshwater strains was short compared to the marine ones. All three Arthrospira strains tested were able to generate H-2 under sulfur (S-) deprivation though the cultures would quickly lose their vitality in S-deprived medium. Interestingly, Arthrospira produced H-2 under nitrogen deprivation, and the H-2 yield was even higher than under S-depletion. However, neither tested chrysophyte nor diatom produced any H-2 under anaerobiosis caused by S-deprivation. Copyright (C) 2011, Hydrogen Energy Publications, LLC. Published by Elsevier Ltd.
