Several activities other than fishing were identified as impacting the marine and coastal environment like waste dumping. These activities result in several forms of habitat degradation including pollution and degradation of water quality. The promotion of healthy aquatic ecosystems is fundamental for limiting pollution.
Echinoderms, which got caught unintentionally while fishing, were either thrown in the fish landing centre as biowaste or used as animal feed. But it can be best used as a pharmacological source by identifying bioactive compounds from them to be used as biodrugs.
Marine organisms are known for their source of structurally novel and biologically active metabolites. The present study is aimed at identifying the anti-bacterial potential of Seaurchin , Temnopleurus alexandri, thrown out as biowaste in the fish landing centre. The anti-bacterial activity of the ethyl acetate extract (20, 200, 2000, 5000 ppm concentrations) of T.alexandri was tested with 7 bacterial strains i.e., Bacillus subtilis, Enterococcus faecalis, Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Proteus vulgaris and Pseudomonas aeruginosa. Except for B.subtilis and K.pneumoniae the extract was effective in controlling the E.faecalis, S.aureus , E.coli, P.vulgaris and P.aeruginosa. Minimum inhibitory concentrations were also found. The chemical composition of ethyl acetate extract was also identified by GCMS.
