ABSTRACT

 

The global warming is due to green house gas emissions resulting from fossil fuels is a serious global environmental problem. Hence it is necessary to shift towards renewable/non- conventional/alternative sources of energy which are bio-mass, bio-fuels, etc. Biomass is a lignocellulosic and abundant renewable resource on earth and includes various agricultural and forestry residues and industry wastes. Ethanol production from lignocellulosic has gained increasing research attention due to their abundance and immense potential for conversion into sugars and fuels. Several technologies are available for the conversion of lignocellulosic to fuel ethanol involved various steps such as pretreatment, enzymatic hydrolysis (saccharification) and fermentation. In the biological pretreatment processes, Aspergillus species fungi are the most effective biological pretreatment of lignocellulosics materials. The deseeded sun flower heads was used for the present study at different pH values at 30oC temperature for the fungal pre- treatment and yeast fermentation for the production of ethanol (1.9%). The deseeded sunflower head are characterized by the XRD, SEM, FTIR and particle size analysis.
