Lignocellulosic wastes are used as feed stock since are abundantly available. The basic problems involved with bioethanol production from lignocellulosic wastes are high consumption of chemicals used for saccharification, delignification and glucose availability. These problems are considered as important themes of the present study. Ultrasound assisted saccharification was carried out using sa...

The lignocellulosic wastes produced in food industries are suitable raw materials for the production of biological products. In this study, the solid state fermentation of Aspergillus flavus on lignocellulosic wastes was evaluated for microbial protein production. The fraction of the full factorial method was applied for experiment design and process optimization. The results analysis was perfo...

The lignocellulosic biomass (especially agricultural wastes) is known to be an excellent carbon source for microbial enzyme production. In this paper, the cellulase production from lignocellulosic materials under solid state fermentation (SSF) was investigated. The effects of fermentation conditions, such as moisture content, initial pH, temperature, and composition of mixed substrate (wheat st...

Rising energy prices and depleting reserves of fossil fuels continue to renew interest in the conversion of biomass to biofuels production. Biofuels derived from renewable feedstocks are environmentally friendly fuels and have the potential to meet more than a quarter of world demand for transportation fuels by 2050. Moreover, biofuels are expected to reduce reliance on imported petroleum, redu...

Palm oil solid wastes consist of cellulose, hemicellulose and lignin. In this study, a single stage of acid hydrolysis process of palm oil empty fruit bunch (EFB) for production of fermentable sugar was carried out under moderate temperature (45°C) and ambient pressure. The effect of four different process variables such as solid size, HCl concentration, solid percentage and temperature were in...

Background With growing concern in obtaining clean and renewable energy, many works in bioenergy has been developed in order to obtain substantial gains for the environment. Due to the large environmental impact associated to the use of fossil fuels, ethanol production from lignocellulosic materia lhas been widely explored, aiming environmental, economic and social benefits. Lignocellulosic bio...

Abstract Bioenergy is a critical part of renewable energy solution to today’s energy crisis that threatens world economic growth. Corn ethanol has been growing rapidly in the past few years. Policy-makers and researchers alike are becoming aware that corn ethanol has some serious drawbacks. It adversely impacts food prices and is harsh on soil fertility. Lignocellulosic ethanol on the other han...

Lignocellulosic wastes are abundant, renewable and inexpensive sources of energy. This wastes contains large amount of residual plant biomass which is non edible material obtained from plant cell walls. Biomass could be obtained from crop, domestic liquid fuel, municipal solid waste and agricultural residuals. In nature, cellulose, hemicellulose and lignin are major component of plant biomass t...

Ethanol obtained from biomass has potential to become an important sustainable transportation fuel in the near future. Renewable energy sources, such as lignocellulosic biomass, are environmentally friendly because they emit less pollution without contributing net carbon dioxide to the atmosphere. Among kinds of biomass, lignocellulosic biomass is a very useful feedstock to economically produce...
