Obligate aerobes are organisms that need oxygen to survive and multiply. There are some interesting examples of obligate aerobes in the microbial... for Teachers for Schools for Companies Written By: Aerobe, an organism able to live and reproduce only in the presence of free oxygen (e.g., certain bacteria and certain yeasts). Organisms that grow in the absence of free oxygen are termed anaerobes; those that grow only in the absence of oxygen are obligate, or strict, anaerobes. An obligate aerobe is an organism that needs at least 20% oxygen in its surroundings to grow. The term obligate, as in 'obligatory' or 'required,' suggests that oxygen is absolutely essential for the survival and multiplication of obligate aerobes. Aerobe: Aerobe,, an organism able to live and reproduce only in the presence of free oxygen (e.g., certain bacteria and certain yeasts). Organisms that grow in the absence of free aerobic, adj. Aerobe An organism that must (obligate aerobe) or is able to (facultative aerobe) live in an O2-containing environment, and which may use O2 as the terminal electron acceptor in respiration. aer·obe (ār'ōb) facultative aerobe one that can live in the presence of oxygen, but does not require it. Obligate aerobes are organisms that need oxygen for their survival and multiplication example plants, animals, and fungi. Not all microbes are obligate aerobes; some have the ability to survive in the absence of oxygen. Video: Obligate Aerobes: Definition & Examples Obligate aerobes are organisms that need oxygen to survive and multiply. There are some interesting examples of obligate aerobes in the microbial world. Obligate aerobes use oxygen as final electron acceptor in the electron transport chain to produce energy in the form of ATP (adenosine triphosphate). This gives them the advantage of producing more energy than other organisms that are not obligate aerobes. aerobe An organism, especially a bacterium, that requires oxygen or air to live. Some bacteria are ANAEROBIC. aerobe any organism (typically a microorganism) that can survive only in the presence of oxygen required for AEROBIC RESPIRATION. Aerobe
