Diversity, marine sponges, Demospongiae, Sethubavachatram village, Lysinibacillus macrolides, silver nanoparticles



Spongiidae is a family of sponges comprised of seven species ranging in shape and size from small and low-lying to towering and gigantic. For instance, the Hyattella species from India has been described in a perplexing way.


The primary objective is to morphologically identify a marine sponge from Sethubavachatram village in Tamil Nadu, India. Then to identify the bacteria associated with the sample to synthesize silver nanoparticles and to know antimicrobial property of the samples.


The sponges is identified by morphology and found to be Hippospongia intestinalis. The bacteria associated with the sponges is Lysinibacillus macrolides. Silver nanoparticles were synthesikzed and analyzed by SEM and TEM.


The antimicrobial assay confirmed that the synthesized particles are effective in inhibiting disease causing bacterial and fungal strains.
