Microorganisms play an important role in decaying dead organisms and enriching the soil. They break down complex compounds into simpler ones that plants can use. Herbivores rely on bacteria in their stomach to digest cellulose from plants. Certain bacteria also live in human intestines and help with digestion while destroying harmful microbes. Some microbes like Penicillium molds produce important antibiotics that can treat diseases. Genetically engineered bacteria can produce vaccines and insulin. Microbes are crucial in agriculture by releasing nitrogen that plants need and in various industries through fermentation processes.

1. USEFUL MICROORGANISM

2. ROLE OF MICROORGANISM

3. Decayingprocess

4. DecayingprocessManybacteria help decompose (menguraikan) deadorganism and animal wastesintochemical compound such as ammonia.In sewagetreatment plant ( lojirawatankumbahan), bacteria are use to break down the complex animal and plant matterinto simple compounds

5. What is the benefit (kebaikan)?Its enriches the soil and makes essential substances available to plants in a form that they can use.iamenjadikantanahlagisuburdanmembekalkansebatian yang diperlukanolehtumbuhan.

8. ROLES MICROORGANISM IN DIGESTION

9. ONE OF THE MAIN COMPONENT OF PLANT IS CELLULOSE

10. Cellulose is hard to digest by the animal….How they digest the cellulose…?Cellulose can be digest by enzyme named cellulase.How they can get cellulase?

12. Herbivores depend on bacteria that live in their stomach to digest cellulose

13. This bacteria secretes (merembeskan) cellulase into the stomach

14. Beside’s animal?

17. FOOD DIGESTIONCertain kinds of bacteria live in intestines of human (ususmanusia) and other microorganism.Why they live in our intestines?They help in digestion and destroy harmful microorganism.

18. BACTERIA THAT HELP IN DIGESTION….Lactobacillus AcidophilusBifidobacteriaStreptococusThermophilusLactobacilusBulgaricus

19. Where we can find this bacteria except in intestines ?YOGURT YAKULT

20. MEDICINESome type of microorganism produce important drugs called ANTIBIOTICS..Functions of antibiotics….Weaken Destroy other microorganismPenicilliumnotatumis a GREEN MOULDIts produces antibiotic calledPENICILLIN

22. Disease That Can Cured By Using Penicillin

24. Genetically enginereedSome bacteria have been genetically engineeredWhy?To produce certain vaccines that are used to prevent infectious disease.Produce insulin which used to treat diabetics

25. AGRICULTUREBacteria play important roles to promote the plant growth..BacteriaBreak down dead plants and dead animals by releasing AMMONIA

26. AMMONIAAdds nitrogen into the soil (tanah)The nitrogen fixing bacteria in the soil change the ammonia into nitrates.This nitrates will be used by plantsnitrogen fixing bacteriaAmmonia Nitrates

27. Why plants need nitrates?They need nitrates to make aminoacidsBut…………………………….Pea and bean plants use bacteria Rhizobiumwhich directly convert nitrogen into acid aminoNitrates Amino acids

28. RhizobiumbacteriaLive in plant roots

29. INDUSTRYBacteria are used in the production ofMilkYogurtCheese Vinegar Soy sauce Chocolate Certain vitamin BCitric acids

30. Production of breadYeast causes the bread to rise by producing carbon dioxide from the carbohydrates in the dough.Carbon dioxide gas bubbles released in the dough causes it to rise.So the bread become fluffy

32. YEAST

33. Production of milk, yogurt n cheeseCertain bacteria are used in the production of milk, yogurt and cheese.This process called as FERMENTATION
