3. Aquatic microorganisms Introduction Microorganisms as Marine products CONCLUSION Antimicrobial source Biosurfactant Biofuel source

4. Introduction

5. Definition The aquatic environmentcovers approximately 70% surface of the earth - Marine microorganism have unique properties since they have to adapt to extreme marine environment conditions

6. Aquatic microorganisms Introduction Microorganisms as Marine products CONCLUSION Antimicrobial source Biosurfactant Biofuel source

7. Marine microorganisms as antimicrobial source There has been a great interest from researchers to explore marine microorganisms as new source of antibacterial compounds as increasing resistance of pathogen to present antibiotics.

8. Marinomonas mediterranea isolated from Marinomonas mediterraneaThe Mediterranean Sea Synthesizes Marinocine

9. Lysozyme enzyme isolated  from disrupt LysozymeMarineCandida albicanscell wall

10. Aquatic microorganisms Introduction Microorganisms as CONCLUSION Marine products Antimicrobial source Biosurfactant Biofuel source

11. Marine microorganisms as Biosurfactant Biosurfactantsproduced by some marine microorganisms have been used for the bioremediation of the sea polluted by crude oil. Example:Species that can produce polymeric biosurfactant isPseudomonas nautical.

12. Aquatic microorganisms Introduction Microorganisms as Marine products CONCLUSION Antimicrobial source Biosurfactant Biofuel source

13. Biofuel sources 1-Biofuels burn cleaner than fossil fuels, releasing fewer pollutants and greenhouse gases, such as carbon dioxide, into the atmosphere. 2-The burning of an enormous amount of fossil fuel has increased the CO2 level in the atmosphere, causing global warming.

14. Energy crops as a biofuelsource made from plants - as a way to decrease the world's consumption of fossil fuels

15. some energy crops compete with food crops for land, creating problems like higher food prices and deforestation

16. Marine microorganisms as a biofuel source -Aquatic microorganisms (AMOs) currently being explored for advanced biofuel production include multiple species of microalgae, cyanobacteria, and other microorganisms.

17. Algae as a biofuel source -replacement of all vehicular fuel with biofuels by using algae that have a natural oil content greater than 50%. -This oil-rich algae can then be extracted from the system and processed into biofuels, with the dried remainder further reprocessed to create ethanol. -In addition to its expected high yield, algaculture — unlike crop-based biofuels — does not entail a decrease in food production, since it requires neither farmland nor fresh water.

18. Statistics -In fact algae can produce up to 250 times the amount of oil per acre as soybeans.   Algae produce 7 to 31 time greater oil than palm oil. It is very simple to extract oil from algae.

19. Application of algae-biofuel Two of three airlines were testing the commercial use of algae-based fuels in flight. Airlines reported that the test flight was successful.

20. The biofuel would perform just like traditional jet fuel without modification of the engines or the aircraft. A4 percent increase in energy density in the fuels because of the lower-burning temperatures in the engine.

21. Aquatic Species Program (ASP) more than US$25 million was invested in this program Researchers in the ASP established a collection of 300 most promising strains, most of them green algae (Chlorophyceae) and diatoms (Bacillariophyceae). Microalgae collection and screening:

22. Aquatic microorganisms Introduction Marine products CONCLUSION Microorganisms as Antimicrobial source Biosurfactant Biofuel source

23. Biopterin glucose protect from effect of UV-A radiation Antibiotics agents MARINE PRODUCTS 4-hydroxybenzoate as preservatives in variety of food

24. Photobacteria research is one of many subspecialties of marine microbiology. The study of bioluminescence (the biological generation of light).

25. Aquatic microorganisms Introduction CONCLUSION Microorganisms as Marine products Antimicrobial source Biosurfactant Biofuel source

26. CONCLUSION To date, only a very small proportion of the study regards to marine environment exploration has been developed. It can help in speed up the discovery of useful product from marine microorganisms for the benefits of mankind. Marine microorganisms can be very useful in various industrial fields.
