What is associated with methanogens?
Anaerobes is associated with methanogens.
Why will obligate anaerobes grow in thioglycollate?
Obligate anaerobes do not need or use oxygen as a nutrient. In fact it is a toxic substance to them which either kills or inhibits their growth. Thioglycollate allows obligate anaerobes to grow because it consists of sodium thioglycollate, thioglycollic acid and L-crystine which reduce oxygen to water. This creates an anaerobic environment allowing obligate anaerobes to grow.
Why is a gaspak anaerobic jar necessary for the culture of anaerobes on TSA plates but not in tubes of FTM?
TSA plates do not allow for the growth of anaerobes, becasue the entire culture is exposed to oxygen. So the TSA plates require the gaspak to provide an anaerobic condition. FTM does allow for the growth of anaerobes and aerobes. Anaerobes will be found deep in the soln. away from the oxygen, and aerobes will be found at the top, with facultatives inbetween.
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.
List two forms of anerobes?
* 1.) Obligate Anaerobes (can live only oxygen-free environment)* 2.) Facultative Anaerobes (can live oxygen including environment, but makes anaerobic fermentation)
How do you think these bacteria obtain food and energy?
They are anaerobes and do not need oxygen. They are consumers and make energy by fermentation.
What term is used to describe prokaryotes that can only get energy without oxygen?
Anaerobes
Bacteria that are obligate anaerobes release energy from food by?
Fermentation
What anaerobic organism uses fermentation to convert energy?
Anaerobes all use fermentation.
What is the difference between obligate aerobes obligate anaerobes?
aerobes are those which require free molecular oxygen about 21% in air while facultative anaerobes can survive in both conditions presence and absence of oxygen
Is mycoplasma aerobes or anaerobes?
most of them are facultative anaerobes. oxygen is not pioson for them. M. pneumoniae is aerobe. there are also some strict anaerobes in bovine rumen.
Bacteria that only grows with the absence of oxygen?
Bacteria that can ONLY grow in the absence of oxygen are called obligate anaerobes.
Can obligate anaerobes grow on a slant that is incubated anaerobically?
Do obligate anaerobes grow on a slant if they are incubated anaerobically?
Are plants anaerobes?
Plants in general do cellular respiration hence these are aerobic organisms. However, seeds remain viable for pretty long time during anaerobic conditions.
What is associated with methanogens?
Anaerobes is associated with methanogens.
Why can media such as brain-heart infusion and thioglycollate be used for the cultivation of anaerobes?
Anaerobes cannot be cultivated in the presence of atmospheric oxygen.
Why will obligate anaerobes grow in thioglycollate?
Obligate anaerobes do not need or use oxygen as a nutrient. In fact it is a toxic substance to them which either kills or inhibits their growth. Thioglycollate allows obligate anaerobes to grow because it consists of sodium thioglycollate, thioglycollic acid and L-crystine which reduce oxygen to water. This creates an anaerobic environment allowing obligate anaerobes to grow.
