Abstract

Continuous hydrogen production from glucose at 75 degrees C was examined at HRTs of 0.67, 1, 2, and 3 d by using extreme thermophilic microflora, which consisted of several subspecies of Caldanaerobacter subterraneus. The maximum hydrogen yield of 3.32 mol-H2/mol-glucose degraded was obtained at the highest HRT, 3 d. Both the maximum volumetric and specific rates of hydrogen production (1.22 L-H2/L/d and 4.15 L-H2/g-VSS/d, respectively) were obtained at the lowest HRT, 0.67 d. A 16S rDNA analysis showed that the community structure of the microflora did not change at any of the HRTs.

摘要

通过使用由地下卡尔厌氧杆菌的几个亚种组成的极端嗜热微生物群落，在75摄氏度下，于水力停留时间（HRT）分别为0.67、1、2和3天的条件下，研究了从葡萄糖持续产氢的情况。在最高水力停留时间3天时，获得了3.32摩尔氢气/摩尔降解葡萄糖的最大产氢量。最大体积产氢率和比产氢率（分别为1.22升氢气/升/天和4.15升氢气/克挥发性悬浮固体/天）均在最低水力停留时间0.67天时获得。16S核糖体DNA分析表明，在任何水力停留时间下，微生物群落结构均未发生变化。
