When testing microaerophiles prefer to use a semisolid nitrate medium that contains small amount of agar Why?
Using a semisolid nitrate medium with a small amount of agar allows microaerophiles, which require reduced oxygen levels, to grow without being exposed to high oxygen concentrations due to the agar's ability to create an oxygen gradient. This setup mimics the low-oxygen environments that microaerophiles thrive in and aids in their growth and identification.
What kingdom is gram positive bacteria?
Kingdom Gram-Positive Bacteria is a kingdom within the domain Bacteria.
What is the difference between bacteria and bacterium?
bacteria is plural and bacterium is singular
What does bacteria have in common with paramecium?
No,Parameacium is not a bacteria but it is a single celled organism which on bacteria
What do bacteria produce?
"Bacteria producing bacteria" - this is not a specific type of bacteria, as you might say a dog is a specific type of animal. All bacteria reproduce, and form new bacteria through a process usually called binary fission. In this way, each bacteria produces more new bacteria. It is not a trait of one species of bacteria.
Account for the subsurface growth of microaerophiles in a shake-tube culture?
Because microaerophiles require Oxygen, but at a low concentration.

Is the pour plate method use full for growing microaerophiles?
Microaerophiles are grown best in an low oxygen environment. If a candle is placed in a jar with the microbe in a broth on an agar, it will remove the oxygen when a lid is placed on the jar. What will grow will be that microbe.
What is microaerophile?
Microaerophiles are microorganisms which are unable to grow when oxygen concentrations reach those found in air (20%) but nevertheless whose growth requires the presence of some oxygen (e.g., 2 to 10%). "Microaerophiles appear to grow best in the presence of a small amount of free oxygen. They grow below the surface of the medium in a culture tube at the level where oxygen availability matches their needs
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.
When bacteria from a throat swab are streaked on blood agar why is the agar stabbed several times with the loop?
first of all the method of stabbing the agar is no only for throat sample but can be for all specimen except for liquid samples such as urine. the second thing is by stabbing the loop, you can save your time to sterile the loop back. and the other thing is to make sure the loop are no hot anymore..
What is a bacteria that infects bacteria called?
Bacteria do not infect other bacteria, but they can attack them.
