Due to the long term availability, low cost and easily available of lignocellulosic biomass (LCB) such as agricultural residues and grasses tends to be a sustainable feedstock for production of biofuel and bio-based products. The LCB to biofuel conversion process involves series of significant steps such as pretreatment, hydrolysis and fermentation. However, the biochemical conversion process faces various technical challenges of being contamination with phenolic compounds, aromatics, aliphatic acids, furan aldehydes, inorganic ions, acetic acid, formic acid, levulinic acid, 5-hydroxymethyl-2-furaldehyde (HMF), vanillin, syringaldehyde, conferyl aldehyde and bioalcohol or other fermentation products. Despite of the existing problems and challenges, LCB is considered as one of the most sustainable potential feedstock used for production of biofuel. The feedstock such as Saccharum spontaneum, Phragmites karka, and switch grass has been extensively explored by many researchers for its bioethanol production. To find a new raw material, that can be utilized as feedstock for biofuel production is another challenged in the bioethanol production. In this regard, we aim to explore the LCB found in Kamrup district of Assam and Thoubal district of Manipur of North-East India for biofuel production. The characterization of lignocellulosic biomass gives prior information about the biomass for its fuel content before going through pretreatment and enzymatic saccharification.
