Abstract

Abstract: Straw is an abundant natural bioresource, especially in developing and agricultural countries. Bio-hydrogen production from this renewable biomass through biological methods is an active research area. Because of its distinctive characteristic of being rich in cellulose, straw has been extensively considered as a promising raw material for clean energy production. In this paper, the recent progress of bio-hydrogen production from straw was reviewed with the emphasis on the advances in pretreatment and hydrolysis technologies. The future development of straw-based biohydrogen production was also analyzed. Based on the physicochemical properties of straw biomass and mechanisms of bio-hydrogen fermentation, various pretreatment procedures have been developed to make the straw substrate more available for hydrogen-producing bacteria to realize large-scale bio-hydrogen production from straw. This review summarized the recent technologies of straw pretreatment and hydrolysis as well as elaborated on the bottlenecks in the field of straw biotransformation in great detail. Furthermore, based on the current technology status and potential, the challenges, prospects and future directions of the production methods were further proposed.
