研究了利用脂质提取微藻生物质残渣生产氢气和甲烷的两阶段工艺。比较了一段法和两段法的沼气产量和能源效率。两阶段反应生成H2/g±2.4 mL挥发性固体（VS）和CH4/g-VS（393.6±19.5 mL）。甲烷产率比单段法高22%。能源效率从一级工艺的51%提高到二级工艺的65%。此外，发现重复分批培养是一种有效的培养方法，可以提高甲烷产量，缩短发酵时间。在重复分批培养中，随着氨水平的升高，甲烷产量略有下降，说明氨的积累可能影响甲烷产量。
A two-stage process to produce hydrogen and methane from lipid-extracted microalgal biomass residues (LMBRs) was developed. The biogas production and energy efficiency were compared between one- and two-stage processes. The two-stage process generated 46 ± 2.4 mL H2/g-volatile solid (VS), and 393.6 ± 19.5 mL CH4/g-VS. The methane yield was 22% higher than the one in the one-stage process. Energy efficiency increased from 51% in the one-stage process to 65% in the two-stage process. Additionally, it was found that repeated batch cultivation was a useful method to cultivate the cultures to improve the methane production rate and reduce the fermentation time. In the repeated batch cultivation, the methane yield slightly decreased if the ammonia levels rose, suggesting that the accumulation of ammonia could affect methane production.
