Obligate aerobes are organisms that thrive in oxygen and require it to live (make ATP for energy). Obligate anaerobes are the exact opposite (require the absolute absense of oxygen to survive, and use fermentation to make ATP). Facultative anaerobes can survive with or without oxygen, but do better with oxygen.
What else can I help you with?
An organism that will die in the presence of oxygen is called a?
An obligate anaerobe.
Bergey's Manual describes Streptococcus and Escherichia as faculative anaerobes How do the oxygen requirements of these organisms differ...Which one could correctly be called an aerotolerant anaerobe?
Streptococcus is an obligate anaerobe and therefore lacks catalase. However, Streptococcus would be considered an aerotolerant anaerobe because, even though it lacks catalase to break down hydrogen peroxide, it also lacks the cytochrome system that would produce hydrogen peroxide in the first place. Therefore, it is not aerobic, but it is tolerant of aerobic conditions.
What organism that can live only in an Oxygen-free environment?
Anaerobic bacteria are organisms that can live in environments with little to no oxygen. They have adapted to generate energy through fermentation or anaerobic respiration. Some examples include clostridium and methanogens.
How microbes are classified based on their oxygen preferences?
On the basis of oxygen requirement microorganisms are classified asAerobes: organisms that use molecular oxygen as electron acceptor.Anaerobes: organisms that use some molecule other than molecular oxygen as electron acceptor.Facultative organisms : organisms that can use either molecular oxygen or some other chemical compound as electron acceptor.
Where would you expect to see growth of a strict aerobe anaerobe microphile and facultative anaerobe in the fluid thioglycollate medium?
The sodium thioglycollate in the broth creates a redox potential in the tube, with higher levels of oxygen at the top of the tube, and a complete absence of oxygen at the bottom of the tube.Fluid thioglycollate broth also typically contains a redox potential indicator such resazurin, which produces a pink color in an oxidized environment. As with the BHI media, organisms will only be able to grow where their oxygen requirements are met, and will localize to the area(s) of their oxygen requirements in the fluid thioglycollate broth.Obligate aerobes will grown on or very close to the top (high oxygen). Obligate anaerobes will only grow on the bottom (no oxygen). Facultative anaerobes will grow throughout but more on top. Microaerophiles will be found in a band where only a small amount of oxygen is found. They would be close to but not on the top.
An organism that will die in the presence of oxygen is called a?
An obligate anaerobe.
What is the different between obligate anaerobe and facultative anaerobe?
Facultative anaerobes does not need o2 to grow but can also grow with o2. Obligate anaerobe cannot grow at all in the presence of o2.
When one inoculates a culture into a test tube containing broth and take it out of the incubator the next day and the culture is growing equally throughout the broth?
faculative anaerobe
Is the rhinovirus an obligate anaerobe?
Hello! The rhinovirus, which is known to cause the common cold in humans, is not an obligate anaerobe. Viruses in general really don't mind if the host they are infecting is an anaerobe or not, and they don't have the organelles and specialised proteins and enzymes required for cellular respiration. However, viruses are obligate intracellular parasites, i.e., they have to infect a highly capable host to reproduce many copies of themselves. Hope this response helped you! 😃
What microorganism causes botulism?
Clostridium botulinum. It is a gram-positive rod, obligate anaerobe, and spore-forming.
A bacteium would be killed by exposing it to oxygen would be a?
A bacterium to which oxygen is cytotoxic is known as an obligate anaerobe.

What is an anaerobe?
An anaerobe is an organism that thrives in an environment without oxygen. Facultative anaerobes prefer an oxygen-free environment but can survive in the presence of oxygen. Obligate anaerobes are destroyed by oxygen and cannot survive if it is present in their environment.
Is micrococcus luteus a facultative anaerobe?
No Micrococcus luteus is aerobic organism, Staphylococcus aureus is often mistaken for Micrococcus luteus but its main difference is that it is a Facultative anaerobe
Is B megaterium a faculative anarobe?
Bacillus megaterium is a facultative anaerobe, meaning it can grow in both the presence and absence of oxygen. This bacterium has the ability to switch between aerobic and anaerobic metabolism depending on the availability of oxygen in its environment.
What organism that can live only in an Oxygen-free environment?
Anaerobic bacteria are organisms that can live in environments with little to no oxygen. They have adapted to generate energy through fermentation or anaerobic respiration. Some examples include clostridium and methanogens.
What organism is killed by atmospheric oxygen?
Obligate anaerobes, such as certain bacteria, are organisms that cannot survive in the presence of atmospheric oxygen because it is toxic to them. Exposure to oxygen can damage their cellular structures and metabolic processes, leading to their death.
