Abstract: In this study, petroleum ether, chloroform and methanol extracts of Codium decorticatum showed the presence of amino acids, carbohydrates, saponins, phytosterols, alkaloids and glycosides. The antibacterial activity against Gram-positive bacteria, such as Streptococcus pneumoniae, Staphylococcus aureus and Gram-negative bacteria, Escherichia coli, Klebsiella pneumoniae, Salmonella typhi, Pseudomonas aeruginosa was carried out using cup-plate method. All the extracts showed good zone of inhibition against S. pneumoniae and K. pneumoniae at the concentrations of 25, 50 and 100 mg mL-1 compared with standard drugs, gentamicin and ampicillin (30 μg mL-1). To standardize the algae, elemental analysis was also carried out on C. decorticatum powder which revealed the presence of various elements. The present findings show the importance of C. decorticatum in producing new compounds having antibacterial activity.
