Antibacterial
Seaweeds cultivated in different parts of the world exhibit varying
antibacterial properties which can be utilized for improving human
health. For example, the extracts of U. fasciata isolated from
the southeast coast of India demonstrated antibacterial properties and a
broad spectrum of antibiotic activity against Bacillus cereus,
Escherichia coli, Bacillus subtilis, Aeromonas hydrophila, Vibrio
fischeri, and Vibrio harveyi (128). Cladophora glomerataexhibited substantial antibacterial activity against the MDR bacteriumAcinetobacter baumannii and various human and fish pathogens,
such as E. coli, B. cereus, Vibrio anguillarum, V. fischeri,
Vibrio parahaemolyticus, and Vibrio vulnificus (129). An acetylenic
sesquiterpene isolated from Caulerpa prolifera, caulerpenyneexhibited antifouling activity against bacteria and the microalgaPhaeodactylum tricornutum (130) . Moreover, the ethanolic extracts
of C. decorticatum displayed antibacterial activity (131). In
this trend there is need for the researcher to explore more and educate
the public and the community in general on the existence and application
several medicinal potentials of seaweed species found in Western Indian
Ocean.
