Abstract
Wastes from the shrimp and fish industry play a contributing role in environmental degradation, pollution and disease. The main objective of this study was to find a medicinal use for shrimp shells and fish scales that would otherwise be wasted in great amounts and to provide the basis for the development of new pharmaceuticals. It was hypothesized that extracts of tiger and white shrimp shells as well as extracts of seabass and red snapper scales would exhibit antibacterial properties. It was further hypothesized that the tiger shrimp extract would inhibit the most bacterial growth. Crude extracts of shrimp shells and fish scales were inoculated into petri dishes containing Klebsiella pneumoniae, Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus and were placed in an incubator for 24 hours at 37 degrees Celsius. The amount of growth that was exhibited by the different strains of pathogenic bacteria was measured in this study and compared against two antibiotic controls, Tetracycline and Penicillin. The preliminary results of this study suggest the effectiveness of shrimp shell and fish scale crude extracts as antibacterial agents against Klebsiella pneumoniae, Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus. Both the shrimp shell and fish scale extracts were more effective in inhibiting bacterial growth than the broad-spectrum antibiotics.
