Abstract

Chloroform, acetone, ethanol and methanol extracts in addition to water extract of three microalgae (Phormidium formusum, Chlorella marina and Navicula f. delicatula) isolated from the Egyptian coast of the Mediterranean Sea, in Alexandria were evaluated for their antibacterial and anti-fungal activities against Staphylococcus aureus and Micrococus luteus, Serratia marcescens, Pseudomonas aeruginosa, E. coli and unicellular fungus (Candida albicans). Data showed that some extracts recorded strong inhibitory activities as compared to standard antibiotics.
