The present study is to investigate the antimicrobial activity of protein hydrolysate of marine water mollusks Babylonia spirata (Linnaeus, 1758)
Antibacterial assay was carried out against four bacterial pathogens by agar well diffusion method and antifungal activity was performed against three human pathogenic fungal strains. 2.6mg/ml protein concentration was estimated by Bradford’s method and 40 to 200 kDa protein bands were resulted in SDS PAGE analysis
Summary
The marine environment is a huge source to discover bioactive natural products. The number of natural products are isolated from marine organisms increases rapidly, and exceeds with hundreds of new compounds being discovered every year (Faulkner, 2002; Proksch and Muller, 2006). Bioactive compounds have been extracted from marine invertebrates, especially sponges, ascidians, bryozoans and mollusks (Proksch et al, 2002). Marine invertebrates offer a source of potential antimicrobial drugs (Bazes et al, 2009). The majority of research on natural products from the phylum Mollusca has been focused on primarily soft-bodies or shell-lessmolluscs, nudibranches and opisthobranches (Karuso, 1987; Faulkner, 1992).
