Anaerobic digestion is well known and well developed technology applied for bioenergy production from different types of feedstock like animal manure, sewage sludge, agricultural residue, industrial waste etc. These different types of substrate are having high content of biodegradable material or organics which make this process an ideal biomass for anaerobic digestion process. Due to the natural intractable structure of lignocellulose biomass towards microbial or enzymatic deconstruction, pre-treatment is necessary to make the celluloses open to enzymatic hydrolysis for fermentation and anaerobic digestions. In recent years, there has been improved concern in pretreatment of lignocellulose biomass and waste for anaerobic digestion. This study was also focussed on the pre-treatment of lignocellosic biomass. In this research, the yield of biogas at 50 V was found to be 90.4 %, 100 V was 83.1 respectively; whereas, without electro-hydrolysis 76.2 % was observed. Moreover, the pretreated biomass gets stabilized at 15th day, but it took more than 18 days for the control or untreated biomass to get stabilize.
