Abstract

The aim of this work was to study the impact of basalt fiber (BF) on hydrogen fermentation of corn straw. The maximum of hydrogen yield and corn straw conversion rate respectively achieved 323.94 mL and 5.23% by adding 1.5 g/L BF particle with the size of 300-400 mesh, which increased by 15.74% and 15.6% respectively than control group. The BF could promote the growth of photosynthetic bacteria, subsequently influencing the products distribution and hydrogen generation. Overall, this investigation demonstrated that BF addition is an effective way to enhance biohydrogen production from corn straw.
