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?
17. FOOD DIGESTION Certain 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 Acidophilus Bifidobacteria StreptococusThermophilus LactobacilusBulgaricus
19. Where we can find this bacteria except in intestines ? YOGURT YAKULT
20. MEDICINE Some type of microorganism produce important drugs called ANTIBIOTICS.. Functions of antibiotics…. Weaken Destroy other microorganism Penicilliumnotatumis a GREEN MOULD Its produces antibiotic calledPENICILLIN
24. Genetically enginereed Some bacteria have been genetically engineered Why? To produce certain vaccines that are used to prevent infectious disease. Produce insulin which used to treat diabetics
25. AGRICULTURE Bacteria play important roles to promote the plant growth.. Bacteria Break down dead plants and dead animals by releasing AMMONIA
26. AMMONIA Adds nitrogen into the soil (tanah) The nitrogen fixing bacteria in the soil change the ammonia into nitrates. This nitrates will be used by plants nitrogen fixing bacteria Ammonia Nitrates
27. Why plants need nitrates? They need nitrates to make aminoacids But……………………………. Pea and bean plants use bacteria Rhizobiumwhich directly convert nitrogen into acid amino Nitrates Amino acids
29. INDUSTRY Bacteria are used in the production of Milk Yogurt Cheese Vinegar Soy sauce Chocolate Certain vitamin B Citric acids
30. Production of bread Yeast 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
