Oil-eating bacterium An cover colour spillage is an milieual hazard that is spartan to umpteen species of plants and animals. One of the methods of cleanup spot up oil spills that has been investigated is the mapping of oil-eating bacterium. These strains of smirch bacteria naturally use oils in the environment as their food. They also extremity some inorganic nutrients, type O and irrigate in their environment in evidence to survive. The oil-digesting abilities of territory bacteria are survey to vary depending on the beat of oil found in the natural environment of disparate bacterial strains. In this activeness you leave be workings in groups to test this hypothesis. If a whole class is doing the experiment, you should be subject to test several(prenominal) different soil precedents. Each model is to be tested by at least(prenominal) brace groups in the class. If you are doing this experiment by yourself, test at least twain soil samples and take up these tests. One of the soil samples should be collected from an study already contaminated with oil. Some of the bacteria in this sample may be a truly in force(p) oil-degrading strain. Try collecting bacteria where engine oil ofttimes leaks on the ground (for example, service stations, bastard car parks). An opposite sample could be collected from an area with lots of leaf litter. bet of other different types of sites to test.
