This text contains detailed descriptions of both the biology and the biotechnological uses of Spirulina Platensis, a blue-green algae (cyanobacteria), which has been recognized and used worldwide as a traditional source of protein in the food industry. Recently the uses and mass cultivation of this valuable alga have risen substantially due to an increased understanding of its biological systems. This comprehensive book contains detailed descriptions of both the biology and the biotechnological uses of Spirulina Platensis. Part 1 focuses on the Physiology, morphology, photosynthesis, and genetics of laboratory cultures. Part 2 discusses the practical uses in biotechnology industries, such as the cultivation, enclosed photobioreactors; mass cultures in open ponds outdoors; uses in wastewater treatment and use of biomass, offering critiques of the problems encountered and discussions of the future commercial prospects for large scale production. Written by the leading experts in this field, it will be an invaluable reference for researchers and industrialists working with this microalga.
