It is one of many products from the pyrolysis of lignocellulose. "Biotechnology for Biofuels" refers to research on biofuels derived from lignocellulose and algae. These chemicals cleave the bonds between the cellulose and lignin components of the lignocellulose. Biomass (cellulose, hemicellulose and lignocellulose) contain vast amounts of fermentable sugars. Lignocellulose is composed mainly of cellulose, hemicellulose and lignin. One of the scientific terms used to denote renewable bioresources is lignocellulose. Lignocellulose refers to plant dry matter (biomass), so called lignocellulosic biomass.
