An aerobic bacteria is an organism that comprises a metabolism based on oxygen. It is a type of bacteria that require oxygen for its growth and survival. The aerobic bacteria’s use oxygen for oxidizing the substrates such as fats or sugars for obtaining energy. Aerobic bacteria contribute largely to the process of decomposition of the organic materials in the soil. Some aerobic bacteria that can make you sick; whereas there are others cause no problems and are very helpful to the human beings.
The aerobic bacteria are microbes that occur naturally causing activities that may have serious consequences on the economy of an industrial environment. The aerobic bacteria may be a result of causing corrosion, fouling, problems of water clarity and bad odors. Adding biocides to water can limit their development and effectively help in managing the water systems.
Quantification of the regular aerobic bacteria by using the dip slides of Kittiwake bacteria offers a visible indication of effective controls and also helps in the identification of the problematic issues in the levels of the bacteria.
There are two types of bacteria: aerobic bacteria and anaerobic bacteria. Aerobic is the one that needs oxygen for its growth and survival; whereas anaerobic is one that do not need oxygen for the same. You can identify easily whether a bacteria is aerobic or anaerobic by growing them in a liquid culture. The aerobic bacteria will start gathering towards the top of the test tube for absorbing more amount of oxygen; whereas the anaerobic bacteria will settle at the bottom for avoiding the oxygen.
Most of the animals, bacteria’s and fungi are aerobes meaning they need oxygen to grow and to breathe. Some of the examples of the aerobic bacteria are Myobacterium tuberculosis, Bacillus, Nocardia and Pseudomonas aeruginosa.
Aerobic Treatments for Sewage Effluents
It uses the naturally occurring aerobic bacteria for breaking the solids and treating its effluents. The contents of the tank, where aerobic treatment has to be used should be well aerated so that the bacteria can survive in it. This can be done by using aerators or blowers. These aerators may be operated for 24 hours a day. For aerobic treatments outside the tank, it is done by “polishing unit”. They are round-ball like objects that are placed on both the sides of the tank and also besides it.
Blood culture for aerobic bacteria: One type of blood culture is used for checking an organism known as aerobic bacteria in an individual. This test is usually performed on those having a weak immune system like very old or young people. Blood samples are taken from the individual for detecting the bacteria in the blood. Two blood samples are required to detect both aerobic and anaerobic bacteria. The blood sample is held at a particular temperature and observed to see if the bacteria grow. Aerobic bacteria require a time period of about24 to 72 hours to grow. If the bacteria grow when exposed to oxygen, it is aerobic bacteria. The aerobic bacteria causing blood infections are Staphylococcus, Neisseria and Pseudomonas aeruginosa.
