Abstract

Abstract Hydrogen is an alternative source of energy of considerable interest, because it is environmentally friendly. Biological hydrogen production processes involving green microalgae are of significant interest. However, until present only few microalgae genera have been studied and almost all of those studies have focused only on cultivation using mixotrophic or heterotrophic media, which are expensive, and can be easily contaminated. This study aimed to compare the potential of biohydrogen production from novel green microalgae under autotrophic and mixotrophic media. A total of ninety strains of six orders of green microalgae were investigated for their capabilities of hydrogen production. The results showed that eleven novel hydrogen-producing microalgae genera were found. The hydrogen production in each order was influenced by the medium. Moreover, several strains presented notable levels of autotrophic hydrogen production and performed at over twice of the mixotrophic medium. These results should be supportive information for the selection and cultivation of hydrogen-producing microalgae in further studies.

自养和混合养条件下微藻产氢的比较

氢是一种非常有趣的替代能源，因为它是环保的。涉及绿色微藻的生物制氢工艺引起了人们的极大兴趣。然而，到目前为止，对微藻属的研究很少，而且几乎所有的研究都集中在使用混合营养或异养培养基进行培养，这些培养基昂贵且容易被污染。本研究旨在比较新型绿色微藻在自养和混合养培养基下产氢的潜力。对6目90株绿色微藻的产氢能力进行了研究。结果发现了11个新的产氢微藻属。各阶产氢量受介质的影响较大。此外，一些菌株表现出显著的自养产氢水平，并在超过两倍的混合营养培养基上进行。这些结果可为今后产氢微藻的选择和培养提供参考。
