چکیده انگلیسی
The feasibility and performance of hydrogen production from paper sludge without inoculation was investigated under thermophilic conditions. The maximum hydrogen production reached 64.32â¯mM with 7.4% PS. The dynamic changes in bacterial community structures during hydrogen production were investigated by analyzing 16S rDNA gene sequences using high throughput sequencing technology. The results showed that microbial community was dominated by order Clostridiales and Thermoanaerobacterales. Genus Thermoanaerobacterium and Ruminiclostridium played a leading role in the fermentation process, which was responsible for the hydrolysis of PS and hydrogen production. Effect of inoculation with Clostridium thermocellum on hydrogen production from PS was also studied. The results showed that C. thermocellum supplement significantly increased hydrogen yield and holocellulose degradation rate by 96.80% and 32.95%, respectively. In addition, inoculation of C. thermocellum enhanced VFA generation and shortened the lag phase of hydrogen production. The present study lays the foundation on the valorization of waste lignocellulose.
