The current book offers insights into the potential for microorganisms in overcoming the worldwide energy crisis. Currently, the energy crisis is a major issue due to the depletion of fossil fuels, which are projected to be exhausted within the next 50 years. Renewable energy, including biomass, is anticipated to be a prominent source of energy in the coming era, with microbes being utilized to extract a variety of biofuels.

This book has been structured into 13 chapters, designed to provide both an in-depth examination and a comprehensive perspective on the role of microorganisms in ensuring the sustainability of humanity. Additionally, it familiarizes readers with the diverse energy-generating pathways among various microorganisms and the different types of biomass energy resources available on the planet, as well as the numerous possibilities for converting these into alternate energy sources with the aid of microbes.

A significant effort has been made to provide readers with a comprehensive understanding of different alternative fuels and value-added products derived from microbes for the 21st century. It is hoped that this book will be beneficial to students and professionals pursuing careers in Microbiology, Biotechnology, Biochemistry, Environmental Sciences, and Energy Studies, particularly in relation to alternative biofuels that may help to resolve the global energy crisis.
