About The Book

This book provides comprehensive and authoritative explanations and assessments of modern cyanobacterial research. Particular attention has been given to the utilization of cyanobacteria in the production of biofertilizers, the use of cyanobacterial metabolites in medicine production, and their potential as human food and protein supplements. Members of this group are effectively utilized across various fields of biotechnology. The book aims to bridge classical and contemporary identification methods, focusing largely on molecular biology. A detailed study on paddy field cyanobacteria in Gangetic West Bengal, featuring meticulous camera-lucida drawings of different species, can aid scholars in future taxonomical research. The book is divided into four parts. Part one provides a comprehensive account of Cyanobacteria, specifically designed for undergraduate and postgraduate students majoring in Botany. Parts two and three focus on Paddy Fields Cyanobacteria of the Lower Gangetic Plain of West Bengal. Part two delves into the taxonomy of blue-green algae, while Part three covers ecological studies on paddy field cyanobacteria. Part four is tailored for researchers, environmentalists, policymakers, agronomists, scientists, and scholars studying microbiology, agricultural ecology, and sustainable farming practices. This book can serve as an introductory text for those preparing for postgraduate degrees in Plant Biotechnology, Botany, and Molecular Biology.
