  1. Classification – Aerobic/Anaerobic; Formal scientific name (anything interesting about name?)  Psudenomas is the name for the petroleum eating bacteria. They are aerobic meaning that they require air to live.
  2. Gram stain – Is the bacteria gram – or gram +. Gram Negative
  3. Structure – shape; cell wall; internal structures; flagella present? Spore forming (endospores)?  Rod shaped and have flagella
  4. Habitat – where would you find this bacterium? Found in soil (everywhere)
  5. Nutritional Requirements – Heterotrophic? Autotrophic? Chemoautotrophic?
  6. Reproduction – Description of its asexual and sexual reproductive strategies. Asexual
  7. History – When discovered; interesting historical information dealing with your bacteria.Observed as early as 1894 but people did not know of their uses until 2000.
  8. Beneficial properties – How is this bacteria helpful to humans, other animals, plants, fungus, protista? Helps to clean up many oil spills around the world. 
  9. Problems associated with the loss of bacteria in the environment? None. But if they do die out it will be harder to clean up oil spills
  10. Interesting or unusual facts about your bacteria.  Although Pseudomonas are very helpful in cleaning up the environment, they can also cause many different diseases. Pseudomonas can cause endocarditis, respiratory infections, bacteremia, central nervous system infections, ear infections, eye infections, bone and joint infections, urinary tract infections, gastrointestinal infections, and skin infections.  These infections only happen when the defenses of the tissue are poorer than normal.  This bacterium is naturally resistant to many antibiotics due to the fact that its outer membrane can withstand them. Pseudomonas can also cause food spoilage because it is able to survive at low temperatures.  One example is in dairy spoilage such as cheese and milk.
