Lignocellulosic biomass as potent feedstock resource for bioethanol production: Recent updates

Non-renewable fossil fuels are unable to fulfil today`s requirements of the societies in terms of energy requirements. The increasing demands for energy have emphasized the researchers to search for alternative sources of energy. Among distinct alternative energy resources, bioethanol has attracted an immense attention worldwide. Currently, lignocellulosic biomasses are considered as the largest renewable resources for the production of bioethanol due to its maximum abundance on the earth. Pre-treated lignocellulosic biomasses are converted into bioethanol by both direct microbial conversion and hydrolysis process along with fermentation. Immobilization and nanotechnology have shown effective roles in the improvement of bioethanol from lignocellulosic biomasses. This review focuses on recent developments in bioethanol production from varied lignocellulosic biomasses as cheep feedstock.
