ABSTRACT
The basic and fundamental requirement for initiating marine cyanobacterial biotechnology is to first enumerate the available cyanobacterial diversity and understand their ecobiological properties. In addition to their widespread geographic distribution, cyanobacteria have probably played a major role throughout the biological history of the earth, cyanobacteria being a prokaryotic organism having potentials of both bacteria and algae, and they can be easily manipulated like bacteria which shows promise in the field of cyanobacterial biotechnology. This review is intended to focus on the biodiversity of cyanobacteria in marine environments of India and future research priorities and opportunities in the commercial utilization in varied areas such as mariculture, food, feed, fertilizer, medicine, industry and combating pollution.
