Marine bacterial species contribute to a significant part of the oceanic
population, which substantially produces biologically effectual moieties
having various medical and industrial applications. The use of
marine-derived bacterial pigments displays a snowballing effect in
recent times, being natural, environmentally safe, and health beneficial
compounds. Although isolating marine bacteria is a strenuous task, these
are still a compelling subject for researchers, due to their promising
avenues for numerous applications Due to their beneficial properties,
including anticancer, antibacterial, antioxidant, and cytotoxic actions,
marine-derived bacterial pigments were desirable in the food,
pharmaceutical, textile, and cosmetic industries. Marine bio-pigments
are preferred over synthetically produced colored compounds due to their
biodegradability and higher environmentally friendly nature. Besides
that, hazardous effects associated with the consumption of synthetic
colors further substantiated the use of marine dyes as color additives
in industries as well. Herein, we have reviewed the potential of
different bacterial species isolated from the marine environment in
diverse studies that produce bioactive pigments with potential
commercial applications, in addition to the biosynthesis and
physiological roles of associated pigments. The chemical structures of
the bioactive compounds are also discussed.
