changes in the microbial community of HPB (hydrogen-producing bacteria). The microbial community of HPB on the 4th day is … show that production of hydrogen and soluble metabolites by the simple microbial community is unstable with fluctuating pH … values at earlier stages (days 1–4). By contrast, the production of hydrogen (51.7–62.0 mL/g-total volatile solids) and …

Trehalose was pretreated by microwave heating with dilute acid to improve glucose yield and hydrogen production during … microwave heating with 1% dilute H2SO4 for 25 min at 120 °C. The hydrolyzed trehalose was inoculated with HPB (hydrogen …-producing bacteria) to produce hydrogen during dark-fermentation. The residual solution of dark-fermentation was reused by PSB …
