Note: This table indicated P. aeruginosa maximally inhibited by methanol extracts
of Perna viridis, Nerita albicilla and Ozius rugulosus. Methanol extracts of marine
invertebrates were also capable to inhibit A. baumannii and E. coli k1 growth
greatly. Low antibacterial activity was seen in case of Perna viridis (gonads) with
minimal inhibition at 21.0% against E. coli K1. Marine invertebrates’ extracts had
the overall best activity against pathogens. |
