"Algae are mysterious and fascinating organisms that hold great potential for discovery and biotechnology."

—Dr. Thierry Tonon, Department of Biology, University of York

"Science is a beautiful gift to humanity; we should not distort it."

—A.P.J. Abdul Kalam

In this book, we emphasize the importance of algal biotechnology as a sustainable platform to replace the conventional fossil-based economy. With this focus, Volume 2 summarizes the up-to-date literature and knowledge and discusses the advances in algal cultivation, genetic improvement, wastewater treatment, resource recovery, commercial operation, and technoeconomic analysis of algal biotechnology.


  • Discusses in detail recent developments in algae cultivation and biomass harvesting
  • Provides an overview of genetic engineering and algal-bacteria consortia to improve productivity
  • Presents applications of algae in the area of wastewater treatment and resource recovery
  • Provides case studies and technoeconomic analysis to understand the algal biorefinery
