    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

    Oxygen Requirements of Bacteria BACKGROUND  The GasPak system is useful for culturing anaerobic bacteria on standard microbiological media because the GasPak generates carbon dioxide and hydrogen. The hydrogen will combine with oxygen present in an anaerobic jar to produce water. This system can reproducibly attain oxygen levels in the parts per million range if used correctly. This is the best method for determining the oxygen requirements of unknown organisms.  A candle jar is useful

    Anaerobic respiration in Bacteria Like humans and other animals‚ bacteria need to breathe. Anaerobic bacteria basically mean bacteria that respire anaerobically. All living cells need to respire in order to release energy for vital cell activities. Anaerobic respiration is respiration in the absence of oxygen‚ hence anaerobic bacteria does not breathe at all. The purpose of respiration is to provide the cell with the appropriate molecules for creating energy in the form of adenosine triphosphate
