- Examples of obligately aerobic bacteria include Mycobacterium tuberculosis (acid-fast), Bacillus (Gram-positive), and Nocardia asteroides (Gram-positive). With the exception of the yeasts, most fungi are obligate aerobes. Also, almost all algae are obligate aerobes.

[2] [6] With the exception of the yeasts, most fungi are obligate aerobes. [1] Also, almost all algae are obligate aerobes. [1] A unique obligate aerobe is Streptomyces coelicolor which is gram-positive, soil-dwelling, and belongs to the phylum Actinomycetota. [7]
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).

In ecology, facultative and obligate are two terms used to describe organisms based on the mechanism of obtaining energy by each organism. Generally, organisms produce energy through cellular respiration. The three main types of cellular respiration are aerobic respiration, fermentation, and anaerobic respiration. The organisms that use either facu...
Facultative refers to the ability to live under more than one specific environmental conditions. The three types of facultative organisms are bacteria, fungi, and endoparasites such as protozoans and nematodes.
Obligate means be restricted to a particular characteristic. Obligate organisms such as bacteria, fungi, algae and endoparasites can be identified in nature. Most algae are obligate aerobes.
Facultative and obligate are two types of organisms categorized based on the types of cellular respiration the used to obtain energy.The three types of cellular respiration methods used by both facultative and obligate are aerobic respiration, anaerobic respiration, and fermentation.Both facultative and obligate can be bacteria, fungi or endoparasites.Definition
Facultative: Facultative refers to the ability to live under more than one specific environmental condition. Obligate: Obligate means to be restricted to a particular characteristic.
Types of Cellular Respiration
Facultative: Facultative organisms obtain energy from aerobic respiration, anaerobic respiration, and fermentation. Obligate: Obligate organisms obtain energy from aerobic respiration, anaerobic respiration or fermentation.
Types
Facultative: A single type of facultative organisms can be identified as facultative anaerobes. Obligate: Two types of obligate organisms can be identified as obligate aerobes and obligate anaerobes.
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.
Aerobic microorganisms require the presence of oxygen for growth. Molecular oxygen functions in the respiratory pathway of the microbes to produce the energy necessary for life. Bacteria , yeasts, fungi , and algae are capable of aerobic growth. The opposite of an aerobe is an anaerobe.
Apr 21, 2024 · The algae are autotrophic protists that can be unicellular or multicellular. These organisms are found in the supergroups Chromalveolata (dinoflagellates, diatoms, golden algae, and brown algae) and Archaeplastida (red algae and green algae).
Obligate aerobes depend on aerobic respiration and use oxygen as a terminal electron acceptor. They cannot grow without oxygen. Obligate anaerobes cannot grow in the presence of oxygen.
