Classify bacteria on the basis of use their oxygen.
Please nhi aata toh Matt do par galat answer Matt dena Ok
Answers
Answer:
Obligate aerobes: They have absolute requirement for oxygen in order to grow. Facultative anaerobes: They are versatile organisms, capable of growth under both aerobic and anaerobic conditions. ... They preferentially use oxygen as terminal electron acceptor.
Answer:
BACTERIA
Oxygen requirements of bacteria reflect the mechanism used by them, to satisfy their energy needs.
Classifications
Facultative Anaerobe
Escherichia coli
Example
an organism which possesses the ability to survive in an environment without oxygen via fermentation or anaerobic respiration.
Facultative Anaerobe
Aerotolerant Anaerobe
Streptococcus
Example
Use for fermentation to produce ATP. They do not utilize oxygen, but they can protect themselves from reactive oxygen molecules. They perform anaerobic respiration.
Aerotolerant Anaerobe
Obligate Anaerobe
Example
Actinomyces
an organism that lives and grows in the absence of molecular oxygen.
Obligate Anaerobe
Vibrio
Example
Microaerophiles
a microorganism that requires oxygen to survive, but requires environment containing lower leveles of oxygen that are present in the atmosphere. Many microaerophiles are also capnophiles, requiring an elevated concentration of carbon dioxide.
Microaerophiles
Example
Campylobacter coli
Capnophiles
Capnophiles
are microorganism that thrive in the presence of high concentrations of carbon dioxide
Example
Mycobacterium tuberculosis
Obligate Aerobe
Obligate Aerobe
an organism that requires oxygen to grow. Through cellular respiration, these organismss use oxygen to metabolise substances.
