Microbial Universe Part 3 Kara Brady Michelle Morris Here’s the video! The Microbial Universe Part III Microbial Universe Part 3 Microbes : a very small form of life microbes include bacteria, fungi, and protozon parasite s. They are too small to se e with the naked eye! Populated by known organisms Es cherichia coli Lactobacillus acidophilus Populated by unkown orgranisms Saccharomyces cerevis iae Sargaso 11 lives in your digestive system to help digest your food everyday! One of the bacteria that turn milk into yogurt! Bakers yeast that makes bread rise. Found in ALL water Freshwater lakes, Oceans , Ponds, Etc. In every sample of water there were more Sar 11 genes than any other organism! Bacterial Plankton IMPORTANT! Sar 11 is important to us becaus e: Possibly one of the most abundant lifeforms on the planet! We know it is involved in someway with the supply of nutrients to alagae, "oxygen producers of the sea" Plays an important role in the food web in the ocean but they don’t know what the role is yet. Focus Questions! How do you know when you’ve found a new organism? How much do we know about microorganisms? What is DNA? What is the new discovered organism in the video? Answers to Focus Questions! When you can’t identify it by appearance, DNA, or Ribosomal RNA. Very little! A complex genetic recipe that consists of two strands held together by four chemicals known as nucleotides. Sargaso Gene #11, SAR 11.
