Production of energy from lignocellulosic biomass or residues is receiving everincreasing interest. Among the different processes, dark fermentation for producing biohydrogen and anaerobic digestion for producing biomethane present considerable advantages. However, they are limited by the accessibility of holocelluloses which are embedded in the lignin network. This paper proposes a review of works on the conversion of biomass into biohydrogen and biomethane with the comprehensive description of i) biomass composition and features that may impact on its anaerobic conversion, ii) the impact of different kinds of pretreatment on these features and on the performance of biohydrogen and methane production.
