What else can I help you with?
Is there a life that doesn't need oxygen?
Yes. There are organisms called anaerobic bacteria which do not need oxygen. To some organisms, called obligate anaerobes, oxygen is actually toxic. The first living things on Earth were obligate anaerobes.
Organisms that are poisoned by oxygen and must live in very low oxygen regions are called?
Obligate anaerobes are poisoned by O2 and use fermentation or anaerobic respiration
Methanogens are or organisms which are poisoned by oxygen?
Methanogens are organisms that are poisoned by oxygen, as they are anaerobic, meaning they thrive in environments without oxygen. Oxygen is toxic to them because it inhibits their ability to produce methane through anaerobic respiration.
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.
Which organism is killed by atmospheric o2?
Anaerobic bacteria are organisms that are killed by atmospheric oxygen. They thrive in environments without oxygen, and exposure to oxygen can be lethal for them.
4 How could you modify the spread plate procedure to enumerate obligate anaerobes?
To enumerate obligate anaerobes using the spread plate method, you would need to perform the procedure in an anaerobic environment, such as an anaerobic chamber or jar. Additionally, you would need to use anaerobic culture media to support the growth of obligate anaerobes. Finally, ensure that the plates are sealed properly to prevent the entry of oxygen during incubation.
Is archaea aerobic or anaerobic?
it can be both depending on the conditions of the environment in which it lives.
20 How do facultative anaerobic bacteria differ from the other two?
Facultative anaerobic bacteria can switch between using aerobic and anaerobic metabolism depending on oxygen availability. Obligate anaerobic bacteria cannot survive in the presence of oxygen and rely only on anaerobic metabolism, while obligate aerobic bacteria require oxygen for survival and use aerobic metabolism exclusively.
What living thing does not need oxygen to live?
Anaerobic bacteria are living things that do not require oxygen to survive. These organisms can produce energy through other metabolic processes that do not involve oxygen, such as fermentation or using alternative electron acceptors.
Bacteria that only grows with the absence of oxygen?
Anaerobic bacteria are microorganisms that thrive in environments without oxygen. These bacteria obtain energy through fermentation or anaerobic respiration. They play important roles in processes like decomposition and digestion.
What are some anaerobic organisms?
clostridium and bacteroides species
