Pretreatment of lignocellulosic biomass is an essential step prior to enzymic hydrolysis to sugars and fermn. to bioethanol. In this work, a one-step process uses aq. ammonia with or without hydrogen peroxide; a proposed two-step process uses aq. ammonia in the first step and hydrogen peroxide in the second step.

Abstract . This thesis focuses on characterization of organic components and inorganic elements in lignocellulosic biomass. The chosen biomass models were mostly wood from conifers and straw from rhizomatous grasses but also forest-based residues and agro-based plants. 2019-01-14 Lignocellulosic biomass is typically nonedible plant material, including dedicated crops of wood and grass, and agro-forest residues. Lignocellulosics are mainly composed of cellulose, hemicellulose, and lignin . Cellulose is a homopolysaccharide composed of Ã-D-pyranose units, linked by Ã-1, 4- Lignocellulosic biomass in the form of organic residues appears to be the most promising option as renewable feedstock for the generation of energy and platform chemicals.

Lignocellulosic biomass (or LC biomass) refers to plant biomass that is composed of cellulose, hemicellulose, and lignin. Biomass is increasingly recognized as a valuable commodity, since it is an alternative to petroleum for the production of biofuels and chemicals.

They can be enzymes that degrade biomass to a mixture of sugars, which can be fermented by microorganisms to produce a wide range of valuable compounds such as fuels, organic acids, alcohols, etc. Lignocellulosic biomass offers the most economical biomass to generate biofuels. However, extensive research is required for the commercial production of an efficient integrated biotransformation process for the production of lignocellulose mediated biofuels.
