Jun 16, 2022 · An obligate aerobe is an aerobe that requires oxygen for aerobic respiration. Obligate aerobes need oxygen to oxidize substrates (for example sugars and fats) in order to obtain energy. They use oxygen as the terminal electron acceptor during aerobic respiration. They have the advantage of yielding more energy than obligate anaerobes.
An obligate aerobe is an organism that requires oxygen to grow. [1] Through cellular respiration, these organisms use oxygen to metabolise substances, like sugars or fats, to obtain energy. [1][2] In this type of respiration, oxygen serves as the terminal electron acceptor for the electron transport chain. [1]
Apr 21, 2024 · Aerobic and anaerobic environments can be found in diverse niches throughout nature, including different sites within and on the human body. Microorganisms vary in their requirements for molecular oxygen. Obligate aerobes depend on aerobic respiration and use oxygen as a terminal electron acceptor. They cannot grow without oxygen.
An obligate aerobe is defined as a microorganism that requires oxygen for its growth and survival (Scheld, 2012). On the other hand, obligate anaerobes are microorganisms that do not require oxygen for growth, and the presence of oxygen can be toxic to them (Lu and Imlay, 2021).
Based on the location and distribution of the bacteria in these tubes, a species can be classified as obligate aerobe, microaerophile, facultative anaerobe, aerotolerant anaerobe, or obligate anaerobe. Figure 2: Microbial oxygen requirements can be determined using thioglycollate agar tubes. The green dots in this diagram represent bacterial ...
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 ...

Are fungi obligate aerobes?
Obligate aerobes cannot survive without oxygen as they rely on it for energy production. Many fungi, including some pathogenic species, are obligate aerobes. These organisms typically grow in environments rich in oxygen, such as soil and decaying organic matter. Obligate aerobes produce more ATP per glucose molecule compared to anaerobic ...
