Abstract

Trehalose was pretreated by microwave heating with dilute acid to improve glucose yield and hydrogen production during dark-fermentation. An optimal glucose yield of 0.95±0.08g/g-trehalose was obtained when trehalose was pretreated by microwave heating with 1% dilute H₂SO₄ for 25min 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 (photosynthetic bacteria) during photo-fermentation. The residual solution of photo-fermentation was reused by MPB (methane-producing bacteria) during methanogenesis. The maximum yields of hydrogen and methane were 731.3±33.6ml/g-trehalose and 116.9±4.3ml/g-trehalose. The sequential generation of hydrogen and methane from trehalose remarkably enhanced the energy conversion efficiency from 47.2±2.2% in hydrogen fermentation to 72.2±3.1% in combined hydrogen fermentation and methanogenesis.
