Aerobes cannot grow in the absence of O2 molecules. Aerobes need oxygen in order to survive and if they do not have it they cannot survive.

What is obligate anaerobe and faculative anaerobe?
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 factors would account for an absence of growth on a streak plate?
* Wrong temperature in the incubator * Not enough time in the incubator * No culture was obtained on the inoculating loop * Wrong type of agar for optimum growth (nutrients,etc.)
What kind of bacterium cannot tolerate oxygen?
The bacterium that cannot tolerate oxygen is Anaerobes, but there are different kinds and each has different tolerances when it comes to oxygen. Obligate Anaerobes can get killed by oxygen. Facultative anaerobes those can grow without oxygen. Aero-tolerant anaerobes they never use oxygen BUT they can tolerate it. Microaerophiles require i tiny bit of oxygen but anymore than the little bit they need and they cannot grow.
Can aerobic bacteria grow in the absence of 02?
no aerobic means it needs air to survive. if there is no oxygen, the bacteri cannot produce a source of food and will die.
Why are bacterial cultures shaken during incubation?
For obligate aerobes, which are bacteria that require oxygen to grow, the shaking of the culture aerates the bacteria sufficiently to allow for growth. Facultative anaerobes also grow well under such conditions since they are bacteria that do not require oxygen, but do grow better under such conditions. Older answer: The culture plated should be inverted (not necessarily shaken) during incubation so that moisture does not collect on the surface of the agar, which could cause clumping of the colonies.
Account for the inability of aerobes to grow in the absence of O 2?
their enzyme system necessitates use of O2 as the final hydrogen (electron) acceptor in the complete oxidative degradation of high-energy molecules such as glucose.
Which bacteria grow in oxygen rich environments?
Obligate Aerobes
Bacteria that only grows with the absence of oxygen?
Bacteria that can ONLY grow in the absence of oxygen are called obligate anaerobes.
What microbes grow on solid media?
coliphages of bacteriophage are seen in solid media
Classify a human with respect to oxygen requirements?
Available Oxygen Microorganisms can be classified according to their oxygen requirements necessary for growth and survival: Obligate Aerobes: oxygen required. Facultative: grow in the presence or absence of oxygen. Microaerophilic: grow best at very low levels of oxygen.
What is a counterpoint to familiarity breeds contempt?
Absence makes the heart grow fonder.
When was Absence Makes the Heart Grow Fungus created?
Absence Makes the Heart Grow Fungus was created on 2008-09-19.
What are strict aerobes?
Is an organism that does not need oxygen to survive and grow - it would possibly die with the introduction of oxygen for example: Clostridium Perfringens. Alex
What does absence makes the heart forget mean?
"Absence", it is said, "makes your heart grow fonder."
What makes the heart grow fonder?
The cliche is "Absence makes the heart grow fonder."
What is a sentence for absence?
Vicki agreed with the old saying that absence makes the heart grow fonder. The word absence is a noun that means the state of not being present.
Why do bacteria reproduce quicker in an aerobic environment?
Not all bacteria do. Some can not grow in the presence of oxygen. Those that do (obligate aerobes and facultative anaerobes) grow quicker in oxygen since it facilitiates their energy cycle and ideal environment.
