Thesis Overview

The project titled "Optimization of Ethanol Production from Lignocellulosic Biomass using Pretreatment and Enzymatic Hydrolysis" aims to address the growing need for sustainable and renewable sources of energy. As the world transitions towards a more eco-friendly future, the utilization of lignocellulosic biomass for ethanol production has gained significant attention due to its abundance and potential to reduce greenhouse gas emissions. Lignocellulosic biomass, which includes agricultural residues, forest residues, and dedicated energy crops, is composed of cellulose, hemicellulose, and lignin. The complex structure of lignocellulose presents a challenge in converting it into biofuels such as ethanol. Pretreatment methods are essential to break down the biomass structure and make the cellulose and hemicellulose more accessible for enzymatic hydrolysis. Enzymatic hydrolysis involves the use of enzymes to break down cellulose and hemicellulose into fermentable sugars, which can then be fermented into ethanol. Optimizing this process is crucial for maximizing ethanol yield and minimizing production costs. Factors such as enzyme type, enzyme dosage, pretreatment method, reaction time, and temperature play a significant role in the efficiency of enzymatic hydrolysis. This research project will focus on optimizing the ethanol production process from lignocellulosic biomass by investigating the effects of different pretreatment methods and enzymatic hydrolysis conditions. The study will involve experimental work to determine the most effective pretreatment method and enzymatic hydrolysis conditions for maximizing ethanol yield. The potential impact of this research includes contributing to the development of more sustainable biofuel production processes, reducing reliance on fossil fuels, and mitigating environmental degradation. By optimizing ethanol production from lignocellulosic biomass, this project aims to promote the use of renewable energy sources and support the transition towards a greener and more sustainable future.
