This handbook covers the different aspects of the aquatic environment, microbiology, and microbial applications. It highlights the role of microorganisms as pollution indicators and bio-control agents.The book covers the impact of pollution on microorganisms, biofilms, cyanobacterial blooms, and the metagenomics approach to isolate microbes.
