Abstract: | Cellulose in wastewater was converted into H2 by a mixed culture in batch experiments at 55°C with various wastewaters pH (5.5–8.5) and cellulose concentrations (10–40 g l–1). At the optimal pH of 6.5, the maximum H2 yield was 102 ml g–1 cellulose and the maximum production rate was 287 ml d–1 for each gram of volatile suspended solids (VSS). Analysis of 16S rDNA sequences showed that the cellulose-degrading mixed culture was composed of microbes closely affiliated to genus Thermoanaerobacterium. |
