Abstract

The agricultural sector has an important place in the economy of our country. Therefore, formation of agricultural wastes is observed to a large extent. Agricultural wastes have a great energy potential. However, these wastes have a complex lignocellulosic structure containing cellulose, hemicellulose and lignin, which are obstructing bioenergy production from lignocellulosic biomass. Therefore, a pretreatment is required to ensure lignocellulose hydrolysis prior to bioenergy production. Biological pretreatment methods distinguish due to its environmentally friendly and economical nature. Rumen microorganisms found in the stomachs of ruminant animals contain microbial consortiums that can hydrolyze lignocellulose biologically. In this literature review, biohydrogen productions from various lignocellulosic wastes pretreated with different methods were reviewed. Rumen microorganisms were suggested as an alternative pretreatment method for biohydrogen production. Optimization of biological pretreatment conditions for the best lignocellulose hydrolysis and hydrogen yield should be done.
