In the present investigation two marine microalgae (Chlorella marina and Navicula f. delicatula) had been chosen for the antibacterial and antifungal metabolites studies. The effects of pH, temperature and light intensity were tested for the production of antimicrobial activity. The antibacterial and antifungal effects of different solvent extracts (chloroform, acetone, ethanol, methanol and water) of two microalgae were tested by agar well diffusion method for their antibacterial and antifungal agent (Staphylococcus aureus, Micrococus Luteus, Serratia marcescens, Pseudomonas aeruginosa, and Escherichia coli) and unicellular fungus (Candida albicans). Data showed that the pH, temperature and light intensity of the medium is very important for growth of microorganisms.
