Enhancement of starting up anaerobic digestion of lignocellulosic substrate: fique's bagasse as an example

► Hydrolytic and methanogenic activity of seven microbial consortia were evaluated. ► Biomethane potential of fique's bagasse as lignocellulosic residue was determined. ► Mixture of inoculums showed a synergy effect improving the biomethane potential. ► Ruminal liquid and pig manure are specific consortia for anaerobic reactor startup.
