Study on the hydrogen production ability of high-efficiency bacteria and synergistic fermentation of maize straw by a combination of strains

Abstract

B2 + X9 was inoculated at the same time, and 6% were inoculated in a ratio of 1 : 1. At an initial pH of 6, the substrate concentration was 12 g L−1, the culture time was 40 h, and the hydrogen production rate of the combined strain was 12.6 mmol g−1.
