The range at which microbes grow best is called it's ?
|
optimum range
|
|
|
The lowest temperature that permits a microbe's continued growth and metabolism is the ? temperature
|
Minimum
|
|
|
The highest temperature at which growth and metabolism can proceed is the ? temperature
|
Maximum
|
|
|
A small range, intermediate between the minimum and maximum, which promotes the fast rater of growth and metabolism is the ? temperature
|
Optimum
|
|
|
Some microbes like ? have a broad cardinal range while others have narrow ones
|
E. coli
|
|
|
A microorganism that has an optimum temperature below 15 degrees C and is capable of growth at 0 degrees C is a ?
|
psychrophile
|
|
|
True pyscrophiles are ? with respect to cold and cannot grow above 20 degrees C
|
obligate
|
|
|
True psychrophiles must be distinguished from Psychrotrophs and ? psychrophiles that grow slowly in cold but have an optimum temperature above 20 degrees C
|
facultative- they can grow with or without something
|
|
|
A lot of ? have adapted to living on or in humans because of optimum heat level created by humans
|
mesophiles
|
|

One of the earliest thermophiles to be isolated was ? It was discovered in Yellowstone's mushroom pool.
|
Thermos aquaticus
|
|
|
The enzyme from Thermos aquaticus that can withstand high heat is the ? polymerase
|
Taq
|
|
|
Once and enzyme was discovered that was capable of copying DNA at very high temperatures(65C-72C), researchers were able to develop a technique called the ?
|
PCR- Polymerase
Chain Reaction |
|
|
The Polymer Chain Reaction can amplify a single piece of DNA into hundreds of thousands of ? copies
|
identical
|
|
|
Taq polymerase acts like DNA polymerase in that it works in semi-conservative replication making copies that are half ? and half ?
