Cyanobacteria continue to produce various biologically active compounds of
antibacterial, antifungal, antifungal, and antiviral potential. These bioactive compounds
also belong to the groups of polyketides, amides, alkaloids, fatty acids, indoles, and
lipopeptides. In addition, these cyanobacteria often produce a broad spectrum of antialgal compounds that attempt to inhibit the growth of pathogens by inhibiting their
metabolic and physiological activities. We all know that cyanobacteria were among the
first microorganisms to live on Earth. Long ago, about billions of years ago, they
played a major role in shaping the Earth into the planet we live on today, and they play
an important role in a variety of functions in addition to our daily lives. Despite the
small genome of cyanobacteria, marine cyanobacteria are also prolific secondary
metabolite producers, along with being an essential source of atmospheric oxygen.
With the ever-increasing human population and higher post-production waste
emissions and increased use of fossil fuels based on food requirements, its
concentration in the atmosphere is expected to increase steadily. Since most of the
attention related to metabolite production has historically been focused on their
freshwater counterparts, marine cyanobacteria present a relatively untapped resource in
terms of evolutionary diversity and industrial potential. They are also producers of
several complex secondary metabolites with potential applications in human health,
biofuels, and bioengineering.
