Summary:

Advances in Lignocellulosic Biofuel Production Systems focuses on general topics such as novel pretreatment strategies, lignocellulosic biomass as a suitable feedstock for biofuels, lifecycle assessment and integrated biorefineries. Furthermore, the book focuses on more advanced topics such as genetically engineered feedstocks, metabolically engineered microbes, bioreactor design and configuration, cell immobilization strategies, artificial intelligence applications and nanotechnology. This book will guide readers through all aspects of lignocellulosic biofuel production rather than simply covering a single topic.
