The world is facing significant environmental challenges due to the over-reliance on fossil fuels, resulting in climate change, air pollution, and energy insecurity. The pursuit of sustainable and renewable energy solutions has driven the advancement of biofuels, which can be produced from diverse biomass sources, including agricultural waste, wood, and algae. Biotechnology has played a critical role in improving biofuel production by enhancing the conversion of biomass into bioethanol, biodiesel, and biohydrogen, among others. Through the application of genetically engineered microorganisms, novel enzymes, and fermentation technologies, biotechnology has contributed to overcoming the limitations associated with conventional biofuel production processes, such as low yields, high energy input, and competition with food crops. This review article explores the current progress of biotechnology in biofuel production, highlighting advancements in microbial fermentation, enzyme optimization, lignocellulosic biomass conversion, and algal biofuels. Key biotechnological strategies such as synthetic biology, metabolic engineering, and cell-free systems are discussed for their potential to improve the efficiency and sustainability of biofuel production. Furthermore, emerging technologies like CRISPR-Cas and advancements in systems biology are analyzed for their future applications in biofuels. Finally, the article examines the economic and environmental challenges faced by the biofuel industry and the future directions that could revolutionize renewable energy from biomass, ensuring greater scalability, affordability, and sustainability. The review concludes by emphasizing the need for continued research into novel biotechnological solutions and collaboration across academia, industry, and government agencies to achieve a sustainable, biofuel-driven energy future. The development of integrated biorefineries, coupled with advanced genetic and fermentation technologies, holds the key to unlocking the full potential of biomass as a renewable energy source.
