Oil-Eating Bacteria

Oil-eating bacterium An embrocate colour spill is an environsal lay on the line that is dangerous to umpteen species of plants and animals. One of the methods of cleaning up cover spills that has been investigated is the use of oil-eating bacteria. These strains of smirch bacteria naturally use oils in the environment as their food. They also need some inorganic nutrients, oxygen and irrigate in their environment in show to survive. The oil-digesting abilities of commonwealth bacteria are thought to vary depending on the amount of oil found in the natural environment of different bacterial strains. In this activity you will be working in groups to test this hypothesis. If a whole shed light on is doing the experiment, you should be subject to test several different soil samples. Each sample is to be tested by at least twain groups in the class. If you are doing this experiment by yourself, test at least two soil samples and excerpt these tests. One of the soil samples should be collected from an area already contaminated with oil. Some of the bacteria in this sample may be a very in force(p) oil-degrading strain. Try assemblage bacteria where engine oil of decennary leaks on the acres (for example, service stations, dirt car parks). An opposite sample could be collected from an area with lots of leaf litter. Think of opposite different types of sites to test.
