Abstract
The aqueous and methanol extract of Callyspongia diffusa collected from south west coast of India were screened for the antibacterial and antifouling activity. The aqueous extract showed inhibitory activity against tested bacterial pathogens E. cloacae, V. fluvialis, V. anguillarum and V. harveyi, S. aureus, Bacillus subtilis, E. coli, Klebsiella pneumoniae, P. vulgaris and Salmonella enterica typhi. The methanol extract exhibited inhibitory activity against V. anguillarum, E. coli, Arthobacter sp and K. pneumoniae. The various concentrations of sponge extracts (10, 100 and 1000 µg/ml) were also analysed for their ability to inhibit the formation of byssus thread by mussels at different time phases. The methanol extract of C. diffusa was more effective in inhibiting the byssus thread formation. TLC and GCMS analysis revealed the presence of long chain fatty acids such as 9, 12-Octadecadienoic acid (Z, Z)-2, 3-di contributing significantly to bioactivities.
