ANTIOXIDANT ACTIVITY OF PHENOLIC COMPOUNDS AS BYPRODUCT OF BIOETHANOL PRODUCTION FROM AGRO-WASTES

Abstract

The present study aims to evaluate the potential of agro wastes such as apple pomace, Grasses, sugarcane bagasse as potential sources 
of bioethanol production. Bioethanol is the one of the recent increasing biofuels due to its positive impact on the environment and 
especially towards second generation of biofuels i.e. from non-food biomass. It’s produced from high sugar and starch containing raw 
materials and lignocellulosic biomass. Lignocellulose may be a complex mixture of carbohydrate that needs an efficient pretreatment 
for the assembly of fermentable sugar, after hydrolysis are fermented into ethanol. Pretreatment of lignocellulose has received 
considerable research globally thanks to economic and environmental sustainability of ethanol production. Microbes like Zymomonas 
mobilis, and Phanerochaete provide sufficient fermentation yield and can be utilized for fermenting lignocellulosic substrate. These 
microbes are isolated from the feedstock samples in the present study. A suitable media was also designed for the growth of the isolated 
microorganisms. The antioxidant tests were analyzed on the potential samples using UV-VIS spectrophotometer. Lowering the cost of 
bioethanol production is one of the biggest challenges currently and can be greatly reduced by utilizing renewable feedstocks. Thus, 
making bioethanol is more economically competitive compared to fossil fuel.
