Issues related to environment, food and energy have presented serious challenge to the stability of nation-states. Increasing global population, dwindling agriculture and industrial production, and inequitable distribution of resources and technologies have further aggravated the problem. The burden placed by increasing population on environment and especially on agricultural productivity is phenomenal. To provide food and fuel to such a massive population, it becomes imperative to find new ways and means to increase the production giving due consideration to biosphere’s ability to regenerate resources and provide ecological services.

Cyanobacteria are environment friendly resource for commercial production of active biochemicals, drugs and future energy (biodiesel, bioethanol and hydrogen).

Topics on isolation, identification and classification of cyanobacteria are discussed, as well as further sections on: summarizing a range of useful products synthesized by cyanobacteria, ecological services provided by cyanobacteria including their harmful effect in water bodies and associated flora and fauna. Chapter on tools, techniques, and patents also focus on the economic importance of the group. This book also provides an insight for future perspectives in each particular field and an extensive bibliography.

This book will be a highly useful resource for students, researchers and professionals in academics in the life sciences including microbiology and biotechnology.
