    species of bacteria look similar under the microscope and also have the same staining results (ex. Gram stain). To be able to differentiate between the different species‚ one can look at the metabolic differences (fermentation)‚ as well as the environmental condition differences (temperature‚ pH‚ oxygen requirements). Being able to manipulate these conditions in a controlled environment can help to correctly identify the exact bacteria. Different media can be used to culture and identify bacteria. Some
